I. PURPOSE

To establish procedures for radiological monitoring and decontamination of  personnel, vehicles, and equipment; and for exposure control, record keeping, and communications relative to an incident at McGuire Nuclear Station (MNS).
 

II. SCOPE

This SOP describes the methods and equipment used to monitor emergency workers and evacuees for contamination. In addition, methods and materials used for decontamination of individuals, vehicles, and equipment are also outlined.
 

III. CONCEPT OF OPERATIONS
 
  A. Direction and Control:
 
    1.

Radiological monitoring and decontamination (RM&D) is the responsibility of Fictitious County Emergency Management. Direction and coordinating instructions will be issued by the Radiological Officer in the Fictitious County Emergency Operations Center (EOC). Upon declaration by the Governor of a State of Disaster, overall responsibility will be assumed by the State Emergency Response Team (SERT). Technical guidance on RM&D activities will be provided by the State Division Radiation Protection (DRP), which has overall statewide responsibility for coordination of radiological monitoring, decontamination, and radiological waste disposal actions.
 

    2. Emergency Worker decontamination stations will be set up at locations specified in Attachment 1. All emergency workers will report to the decontamination station located nearest to their assigned response area after exiting the EPZ.
 
    3. RM&D stations will be established at the locations and operated by the fire departments listed in Attachment 1 as directed by the EOC.
 
  B. Equipment and Supplies:

Inventories of equipment and supplies that are maintained in readiness for use at each RM&D station are stored at the Emergency Management Office and some fire departments. Listing of  equipment and supplies is provided in Attachment 2.
 
IV. EXECUTION
 
  A. The Fictitious County Warning Point will receive initial notification of  an incident at the site. The Warning Point will notify the Fictitious County Emergency Management Coordinator who will evaluate the seriousness of the incident and activate the EOC for direction and control, if necessary. Should off-site emergency response activities be necessary including RM&D, the EOC will coordinate these efforts with the Offsite Response Organizations (ORO).
 
  B. RM&D stations will be set up and/or activated only upon direction of the EOC.
 
  C. Procedures for RM&D operations are contained in Attachments 4 and 5.
 
V. EXPOSURE CONTROL AND POTASSIUM IODIDE

Attachment 3 describes how to use Thermoluminescent Dosimeters (TLD), self- reading dosimeters, and exposure dose record forms for documenting and controlling personnel radiation exposure. In addition, the steps necessary to ensure timely distribution of potassium iodide (KI) to emergency workers is included.
 

VI. COMMUNICATIONS AND REPORTS

Communications between the Fictitious County EOC and each RM&D station will be established to ensure a timely flow of information regarding areas of contamination and incident status. The RM&D officer at each station shall be responsible for maintaining timely communications with the EOC.
 

  A. The primary means of communication will be telephone with fire department radio as back up. If available, amateur radio may also serve as a back-up communications system.
 
  B. RM&D reports shall be made to the EOC:
    1. Upon activation of the RM&D station
    2. Upon first detection of contamination on people, vehicles, and/or equipment
    3. At the request of the EOC
    4. If an individual cannot be successfully decontaminated
    5. To provide facility status reports on at least an hourly basis
 
  C. The EOC will inform the RM&D stations of:
    1. An actual or expected release of radioactivity from MNS
    2. First report of contamination discovered at any RM&D station in the area
    3. Any anticipated large influx of evacuees to the RM&D station
    4. Any information of interest or concern
 
VII. TERMINATION

Following termination of emergency response activities:

  A. Complete activity logs and secure decontamination records
 
  B. Inventory equipment used
 
  C. Replenish supplies
 
  D. Submit report of RM&D activities along with other documentation records to Fictitious County Emergency Management. (The report should contain information such as: time RM&D station was activated, number of people or vehicles processed, special problems, adequacy of procedures and equipment, and recommendations for improvement.)
 
  E. Ensure that all radioactive material is properly logged, tagged, and stored in a controlled area for later disposal.
 
  F. Ensure that RM&D station is monitored and, if contaminated, areas of contamination are marked by rope or tape and signs, and entry by unauthorized individuals prevented (by locked doors, Security personnel, etc.)
 
VIII. INJURIES
 
  A. Information pertaining to possible sick or injured contaminated individuals will be transmitted to Fictitious County EOC for appropriate action.
 
  B. Emergency care of the sick and injured will be provided by Fictitious County EMS in accordance with emergency medical care practices and operating procedures
 
  C. Handling of possible radiation accident patients will be conducted in the manner prescribed in the Fictitious County Standard Operating Procedures for Emergency Medical Services in Support of the McGuire Nuclear Station.
 
IX. RECORDS
 
  A. Radiological Monitoring Teams will maintain adequate records relative to individual exposure, personnel monitoring/decontamination, vehicle monitoring/decontamination, and communications.
 
    1. Individual exposure records will be maintained by each emergency worker who might receive radiation exposure. These records will be maintained on standard forms provided by the Fictitious County Emergency Management Office and will be maintained in the manner prescribed by the instructions on the form (see Attachment 3 Figure 1).  
 
    2. Personnel monitoring/decontamination records will be maintained by the Radiological Monitoring Team at each site where personnel monitoring/decontamination procedures are performed. These records will be maintained on standard forms provided by the Fictitious County Emergency Management Office and will be maintained in the manner prescribed by the instruction on the form (See Attachment 4 Figures 1&,2).

EXPOSURE CONTROL AND POTASSIUM IODIDE (KI) DISTRIBUTION/ADMINISTRATION
 

EMERGENCY WORKERS:

There are two categories of Emergency Workers. Category (1) is defined as Emergency Workers who due to their assignment may have the potential to place them inside the 10 mile Emergency Planning Zone (EPZ) during the accident or will be working in a potentially high exposure rate are (greater than 0.1 R/h). Minimum Dosimetry:  TLD, 0-20 R Dosimeter, and 0-200mR Dosimeter.

Category (2) is defined as Emergency Workers who, due to their assignment, could be exposed to ionizing radiation outside the 10 mile EPZ during the Emergency Phase and possibly inside the 10 mile EPZ during the Ingestion Pathway phase provided the radiation levels will not exceed 0.1 R/h. Minimum Dosimetry:  TLD and 0-200 mR Dosimeter.

For situations where Category (1) Emergency Workers work together as a team in close proximity to each other, TLD and dosimeter may be worn by a designated team member (ex.:  School Bus Drivers). Category (2) Emergency Workers may place dosimeter in a strategically selected work area (ex.:  on wall at decon station).

Emergency Workers should be limited to non-pregnant adults.

Radiation exposure after emergency has ended, should be limited to Federal Radiation Protection Guidance for Occupational Exposure. 5 REM per year Adult. 1/10 500 mRem for minors and the unborn.
 

A. The following devices will be used to maintain adequate exposure control:
 
  1. Low range (0-200mR), high range (0-20R), self-reading dosimeters will be distributed to the Radiological Monitoring Teams by the Emergency Management Coordinator.
    a. Emergency workers shall:
      1) Keep dosimeters on your person while on duty.
      2) Charge dosimeter before initial use and record reading (see Attachment Figures 1 and 2)
      3) If change is under 10 mR (low range), read each 30 minutes; if over 10 mR read each 10-15 minutes.
      4) If reading is over 100 mR, record reading, charge dosimeter (0-200 mR dosimeter).
      5) If accumulated exposure exceeds 1000 mR (1R), notify RM&D Officer, charge dosimeter, and await instructions.
      6) If reading is off-scale for any dosimeter, record, notify RM&D Officer, charge dosimeter, and await instructions.
      7) RADIATION EXPOSURE LIMITSEMERGENCY ONLY
        Exposure control measures will be utilized to assure that the accumulated dose of emergency workers remains as low as reasonably achievable and not to exceed the EPA Guide of:
        * Administrative limit 1,000mR (1R)
        * Turn-back value: 5,000 mR (5R) for all activity
        * Mission Dose-Variable-Incident Dependent
        * By Special Approval: Up to 25,000 mR (25R) 
        * Volunteer ONLY for life saving or protection of large populations: >25,000 mR (>25R)
      8) Notify RM&D Officer of each increase in your accumulated exposure at the end of work shift or as directed.
      9) At end of shift:
        (a) Read dosimeter.
        (b) Record Date, time, and actual reading.
        (c) Subtract initial reading from final reading.
        (d) Record the resultant exposure.
        (e) Add (d) above to accumulated exposures.
        (f) Record the accumulated exposure.
        (g) Compare to guides and limits listed above in this Attachment.
        (h) Charge dosimeter.
        (i) Complete any record forms and keep Personal Exposure Record (Attachment 3 Fig. 1)

TLD’s will be distributed to emergency workers by the Emergency Management Office. TLDs will be returned to the Emergency Management Office at the conclusion of the incident. TLD’s will be read and dose levels analyzed by Division of Radiation Protection.
 

  2. Emergency workers wearing self-reading dosimeters and TLD’s shall:
    a. Wear the self-reading dosimeter and TLD on the front of the body between the neck and waist (ie. left breast pocket unless prohibited by protective clothing).
    b. Wear the self-reading dosimeter outside clothing, including protective clothing to allow easy access for reading dosimeter.
    c. Wear TLD on the first layer of clothing. The TLD should not be worn outside protective clothing (ie. Tyvek coveralls).
    d. Wear TLD with front side facing away from the body. The company name and serial number will be printed on the front side. The TLD should be attached with the spring loaded clip in such a manner to secure the TLD during normal work activities.
    e. Be assigned the same TLD for the duration of the radiation incident or until a switch out for a new TLD is recommended by the appropriate agency. The transfer of a TLD to another emergency worker is prohibited.
    f. Wear a simulated TLD for exercises (ie. of paper cardboard, plastic, etc. to simulate that portion of the emergency plan.) TLD’s will not be worn for exercises or drills.
 
B. KI will be distributed to emergency workers as a blocking agent for the uptake of radioactive iodine by the thyroid.
 
 

NOTE: Have all personnel that are distributed KI read, know and understand the following?
 

  1. Side effects to KI include:
    a. Skin rashes.
    b. Swelling of salivary glands.
    c. Iodism (metallic taste, burning mouth and throat, sore teeth and gums, symptoms of a head cold, and possibly stomach upset and diarrhea.)
    d. Over activity, under activity, or enlargement of the thyroid gland (goiter). This side effect is rare.
 
  2. More serious allergic reactions to KI (POTASSIUM IODIDE) include:
    a. Fever and Joint pain.
    b. Swelling of parts of face and body.
    c. Occasionally severe shortness of breath requiring immediate medical attention.
 
  3. Side effects may occur when higher doses are taken for long periods of time. Only the recommended dose should be taken.
 
  4. Distribution:
    a. It is the responsibility of the Director of the Fictitious County Health Department to ensure that the KI is transported to the pre-determined sites.
    b. The Fictitious County Emergency Management Coordinator will dispatch a vehicle(s) to pick up the KI tablets, instructions, and log sheets delivery to pre-determined sites.
 
    c. The transporter(s) will maintain radio contact with the EOC stating arrival time and departure time from the pick up point as well as arrival time and departure time from each distribution point.
 
    d. Upon arrival at the designated distribution points, the EOC will advise all emergency workers to pick up one (1) bottle of KI per emergency worker with the accompanying information pamphlet. Each emergency worker will be cautioned not to self-administer the KI unless instructed to do so by his or her appropriate supervisor.
 
    e. Upon receipt of the KI, the emergency worker will log his/her name, Social Security #, and emergency assignment on the log sheets at each distribution point. The log sheets will be turned over to the Health Director or designee.
 
  5. Administration:
    a. It is the responsibility of the Director of the Fictitious County Health Department and/or State Health Director to recommend when KI should be self-administered. This recommendation will based on a suspected, projected, or confirmed total thyroid exposure of 25 R or greater.
    b. Unless otherwise directed by appropriate officials, emergency workers will take one (1) tablet only and should not share the remaining tablets with others.
 
  6. Dose:
    a. The KI is supplied in a bottle of 14 white, round, scored tablets containing 130 mg KI.

III. PRECAUTIONS AND LIMITATIONS

Each Personnel RM&D Station worker shall observe the following precautions and limitations:

  A. Immediately divert contaminated and injured individuals, or suspected severely exposed individuals to medical personnel at reception center, as directed by the EOC Radiological Officer.
 
  B. Take care to prevent spreading contamination to uncontaminated areas of the body. Decontaminate more highly contaminated areas first.
  C. Avoid decontamination techniques or duration that could result in abrading or reddening the skin. (Skin damage could result in internal contamination.) Immediately discontinue decontamination efforts if abrasion or reddening is observed, notify the RM&D Officer.
  D. Use lukewarm (not hot) water for washing to reduce the possibility of contamination entering the body through opened pores of the skin. (Cold water will close the pores of the skin trapping contamination, Hot water opens pores allowing contamination to enter skin.)
  E. Exercise caution to prevent contaminated water from getting in the mouth, eyes, ears, or nose or in cuts and abrasions.
 
  F. Collect and secure for later disposal all solid waste, which is potentially contaminated.
 
  G. Instruct contaminated individuals to take care in removing clothing to prevent the spread of contamination. (ie. remove items of clothing without unnecessary shaking or brushing, and carefully place in plastic bags for labeling and holding.)
 
  H. Report contamination levels, which exceed the Action Level (300 CPM)to the EOC Radiological Officer.
 
  I. Keep a clean plastic covering over the probe when is use, and replace it if it gets contaminated. Contamination on the probe cover will be indicated by an increase in the background reading for no apparent reason.
 
  J. Record contamination levels in units of CPM on the Contamination Records.
 
  K. For purposes of this procedure, a “reading” is any amount that exceeds 300 CPM. This is the “reading” or indication when the probe is held stationary for 30 seconds. 
 
  L. Restrict access to all papered walkways and monitoring and decontamination areas until these areas have been checked, determined to be free of contamination, and released for general use.
 
  M. Keep all areas of the RM&D station clean, orderly, and contamination free to the extent practicable during operation.
 
  N. All personnel involved with decontamination will wear a two (2) pair of latex gloves, shoe covers, and coveralls and may be required to wear a face shield depending upon their assignment. All protective clothing items will be in plastic bags. Protective clothing procedures are found in Attachment 4 Figure 7.
 
  O. Decommission and/or release RM&D station areas only after authorization from the EOC Radiological Officer.
 
  P. Injuries to RM&D personnel will be reported to the Radiological Officer at the EOC and handled according to the EMS SOP.
 
IV. INSTRUMENTATION AND SUPPLIES
The instrumentation and supplies needed for RM&D setup and operation are assembled into emergency kits. The contents of these kits are listed in Attachment 2. These kits will be stored at the Emergency Management Office when not is use.
 
V. ACTION LEVEL
  A. The term ACTION LEVEL in this procedure is the radiation level which separates “contaminated” from “uncontaminated.”
 
  B. The Action Level, measured with an Inspector EXP with pancake probe instrument, is defined as follows: Action Level = 300 CPM. 
  C. If the background exceeds 300 CPM, contact the EOC Radiological Officer for guidance.
 
VI. PROCEDURE
 
  A. RM&D Station Setup:
The Personnel RM&D Station should be set up as follows:
    1. Obtain a copy of the appropriate RM&D station diagram.
 
    2. Open and inspect the RM&D Station emergency kit, and report obviously damaged or missing items to the RM&D Officer.
 
    3. Obtain a low range (0-200mR) self-reading dosimeter and a TLD badge, and initiate a Personal Exposure Record Card.
 
    4. Establish the flow paths as illustrated in the RM&D diagram as follows:
      a. Unlock and open all doors affecting the RM&D station.
      b. Roll out and tape paper floor covering for the contaminated walkways.
      c. Attach signs as appropriate for identification and instruction.
      d. Establish barriers if required.
      e. Check the Inspector radiation detection instruments for operability as follows:
 
     

INSPECTOR EXP OPERATIONAL CHECK

      1) Remove survey meter from carrying case.  You must disconnect probe cable from meter before removal. 
      2) Install 9 volt battery (battery cover is located at the bottom on the back of instrument).
      3) Put survey meter back in carrying case and connect probe cable to meter and probe (make sure the connector is properly aligned before rotating connector latching mechanism).
      4) Turn survey meter On/Off/Audio switch to the AUDIO position and set the mode switch to CPM.
      5) Center probe face on check source on case. (Recommend holding probe in direct contact with check source pouch)
      6) Allow at least 30 seconds for reading to stabilize and record reading.
      7) The source reading should be within the range of (X)CPM and (Y)CPM as determined for that unit.
      8) If source check is OK, the meter is ready to use (go to step 9).  If source check does not fall within range readings, redo operational check by making sure the source is centered and allow 1 minute for stabilization.  If source check is out of the proper range reading do not use survey meter.  
      9) Take a background reading in area where no contamination is present (if possible).  Allow meter reading to stabilize for at least 1 minute.  Record reading at the end of the 1 minute time period.  Multiply this reading times 5 and record for later reference.
      10) Cover probe with supplied plastic cover (do not use the RED plastic cover that is used to protect the pancake tube from physical damage).  Clear plastic kitchen wrap can be used to cover the probe or other thin plastic.  Secure plastic cover so that no part is hanging down from probe that would touch the area to be surveyed.  
       

(end procedure for instrument check)
 

    5. Perform the operability test prior to first use of the instrument and at least hourly during operation.  Determine the background readings in the areas of the RM&D station where monitoring is to be performed.
    6. Determine the Action Level (see Section V.).
    7. Dress in Protective clothing.
    8. Notify the EOC Radiological Officer that the RM&D station is ready for servicing evacuated individuals.
    9. Coordinate with the Reception Center Manager to ensure that all evacuees are routed through the RM&D station after the EOC has directed radiological monitoring to begin.
 
  B. Initial Personnel Monitoring:
Every evacuee entering the reception center through the RM&D Initial Monitoring Point shall be checked for contamination if the EOC Radiological Officer has instructed the RM&D Officer to start processing. (This requirement applies also to emergency workers and other personnel arriving at the reception center and/or Emergency Worker Decontamination Center from an evacuation zone or who may have come in contact with contamination (ie. at a vehicle RM&D station.)
 
    1. Initial monitoring shall be performed as follows:  INSPECTOR EXP MONITORING TECHNIQUE
      a. Start survey of possible contaminated surface (person, equipment or vehicle) by keeping the probe face approximately 1” from the surface and moving approximately one inch per second.
      b. Listen for the change in the audio clicks.  Do not look at the meter reading while moving probe (exceptions might be for high noise area then you may need to monitor the meter and/or count light indicator).  For poor light conditions either use a portable hand held light (flashlight) and/or the count light indicator)
      c. If a reading higher than 300 CPM or approximately 5x background (refer to reading calculated in step 9 of meter setup) is detected, continue to monitor that area slowly until the highest count rate and the size of contaminated area is determined.  Record the results on the appropriate form and continue the monitoring process until entire surface is checked.
      d. If probe becomes contaminated, remove plastic cover and replace with clean plastic. Clear plastic kitchen wrap can be used to cover the probe or other thin plastic.  Secure plastic cover so that no part is hanging down from probe that would touch the area to be surveyed.
      e. After monitoring is complete turn survey meter to “OFF” position and remove battery.  Store survey meter in the appropriate container.
 
    2. Meter Reading Below Action Level:
      If no contamination is detected, direct the person to the assembly area for registration, (ALL EVACUEES MUST BE REGISTERED BEFORE LEAVING THE RECEPTION CENTER (Attachment 4 Figure 1). No further action is required at the RM&D station.
 
    3. Meter Reading Above Action Level:
      a. If contamination is detected, start a Contamination Record (Attachment 4 Figure 2) and complete the “Personal”      information and “Monitoring” data sections to the greatest extent possible. Indicate contaminated areas on the “Body Diagram”.
      b.. If the contamination appears to be located in the eyes, ears, nose, mouth, or in cuts and abrasions, medical supervision will be required for decontamination. Inform the RM&D Officer who will contact the EOC Radiological Officer for instructions.
      c. If medical supervision is not required (contamination not in eyes, ears, etc.), escort or direct the person to the Decontamination Area. Send the Contamination Record along with the contaminated individual.
 
  C. Decontamination:
Examine the Contamination Record for the individual, and determine the most appropriate decontamination procedure.
 
    1. If contamination appears to be on clothing or other personal property:
      a. Instruct the individual to remove any valuables (wallet, keys, etc.) from clothing and place the valuables on a nearby bench, table, etc. as directed by personnel conducting the monitoring. (See Paragragh “d” of this section for further)
      b. Instruct the individual to remove clothing, place it in a plastic bag and tape the bag closed.
      c. Instruct the individual to remove any jewelry suspected of being contaminated.
      d. Monitor all items of value (wallet, jewelry, etc.)
      1) If contamination is less than the Action Level, return the valuables to the individual following any further decontamination.
      2) If contamination exceeds the action Level, place the valuables in a plastic bag (not the clothing bag), and tape the bag closed.
      e. Label each bag with the individual’s name and affix a “CAUTION RADIOACTIVE MATERIAL”  sticker or tag.
      f. Complete a Contaminated Property Form (see Attachment 4 Figure 5). Attach a copy to the Contaminated Record Form and give the individual a copy.
      g. Store personal property in the designated area.
      1) The RM&D Officer will coordinate with Reception Center Manager to designate an area for  the storage of personal property.
      2) If valuables, such as jewelry, accumulate to a level where security becomes advisable, the RM&D Officer will coordinate with the Reception Center Manager to request law enforcement support from the EOC.
      3) If an individual does not wish to surrender personal property, the individual will be detained in a designated area and the EOC Rad Officer will be contacted for instructions.
 
    2. If contamination appears to be on intact, non-facial skin surface, the following method should be used for decontamination. Take successive steps only if previous steps are unsuccessful !
      a. Wash the affected area thoroughly for two (2) or three (3) minutes with a good lather using mild soap and lukewarm water, paying particular attention to cracks and crevices i.e., between the fingers, under fingernails, body folds, etc. If contamination is wide spread, have the individual shower.
      b. Rinse with lukewarm water.
      c. Blot dry the affected area.
      d. Re-monitor the areas that have been decontaminated.
 
    3. If contamination above the Action Level remains on skin surfaces after the first decontamination effort, then additional washing may be used:
      a. Wash thoroughly with a mild soap and water, scrubbing with soft bristle brush.
      b. Wash using lukewarm water for five (5) minutes ensuring that only light pressure (not enough to deform bristles of brush) is used. DO NOT CAUSE REDDENING OF THE SKIN.
      c. Rinse thoroughly with lukewarm water.
      d. Blot dry the affected area.
      e. Re-monitor the areas that have been decontaminated.
 
    4. If contamination above the Action Level remains on skin surfaces after repeated washing, inform the RM&D Officer who will contact the EOC Radiological Officer for instructions.
 
    5. If contamination is confined to the extremities and the methods listed above are inadequate, the following sweating technique should be used:
      a. Coat the extremity with a lotion such as “Vaseline Intensive Care.”
      b. Place the extremity in a plastic glove, bootie, or bag and tape shut.
      c. Place the extremity near a source of heat for approximately ten (10) to fifteen (15) minutes or until profuse sweating begins. d. Remove the plastic, wash and rinse thoroughly in lukewarm water.
      d. Blot dry the affected area.
      e. Re-monitor the areas that have been decontaminated.
 
    6. If contamination appears to be on the face, then special care shall be taken:
      a. Using cotton swabs, cloth, or paper towels; a mild soap and lukewarm water, wipe in a direction away from eyes, ears, nose, and mouth.
      b. Properly dispose of all materials.
      c. Blot dry the affected area.
      d. Re-monitor the facial area.
      e. Continue this process until the contamination is below the Action Level, or the process is determined not to be effective. STOP IF SKIN APPEARS TO BE IRRITATED. DO NOT CAUSE REDDENING OF THE SKIN. NOTE: DO NOT USE CITRIC ACID, “PHISOHEX”, OR PERMANGANATE SOLUTION ON THE FACE.
      f. If facial contamination initially exceeds 300 CPM, inform the RM&D Officer who will contact the EOC Radiological Officer for instructions.
 
    7. If contamination appears to be in the hair:
      a. Shampoo with a mild shampoo and lukewarm water, taking care to avoid splashing other areas of the body or allowing water to enter eyes, ears, nose, or mouth.
      b. Rinse with lukewarm water.
      c. Dry the hair.
      d. Re-monitor the decontaminated area.
 
    8. Follow-up Monitoring:
      a. Re-monitor the areas that have been decontaminated.
      b. If contamination above the Action Level remains on skin surfaces after repeated washing, or you notice ANY REDDENING OF THE SKIN, inform the RM&D Officer who will contact the EOC Radiological Officer for instructions.
      c. If contamination in the thyroid area still exceeds the Action Level, inform the RM&D Officer who will contact the EOC Radiological Officer for instructions.
      d. Perform a thorough monitoring of the entire body to ensure that no undetected contamination remains.
      e. Provide clean clothing (if necessary), and instruct the individual to proceed to the assembly area for registration. If decontamination was not completely successful, instruct the person to remain at the shelter facility until the RM&D Officer determines if follow-up medical attention will be required.
      f. Complete the Contamination Record and return it to the RM&D Officer.
 
    9. Decommissioning and release of RM&D areas Potentially contaminated RM&D areas shall be monitored and decontaminated, if necessary, prior to releasing these areas for unrestricted access and use. The procedure is as follows:
      a. Ensure that all potentially contaminated personal belongings in the area to be released are bagged, identified, and marked with a “CAUTION RADIOACTIVE MATERIAL” sticker or tag in accordance with Section VI. C. 1. e. Place these bags in a locked room for later disposition.
      b. Collect all contaminated waste in the area and ensure that it is bagged, identified, and marked with a “CAUTION RADIOACTIVE MATERIAL” sticker or tag. Place these bags in a locked room for later disposal. Do not mix bags of waste with bags of personal belongings.
      c. Monitor the areas for surface contamination after all temporary floor coverings have been removed
      d. If contamination, which exceeds the Action Level, is present, the area must be decontaminated prior to removing access restrictions. A temporary alternative may be to tape clean paper over the contaminated area and to identify this area as requiring later decontamination. This temporary alternative should not be used for areas likely to get wet (ie. around showers or sinks).
      e. Contact the EOC Radiological Officer for specific instructions for area decontamination. The general procedure is as follows:
      1) Put on anti-contamination clothing. (The minimum will be rubber shoe covers and gloves.)
      2) Clean the surface using detergent and wet rags or mops. CAUTION: Do not use a broom or similar dry procedure for decontamination. Do not allow potentially contaminated water or other decon solutions to spread to clean areas
      3) Remove residual detergent using clean, wet rags or mops, and dry the surface.
      4) Re-monitor the Area.
      5) Repeat if necessary.
      6) Select a different decontamination method if the previous method is ineffective. (Contact the EOC Radiological Officer.
      f. When contamination levels are less than the Action Level and all potentially contaminated items have been removed, the are a may be released for unrestricted access and use.
      g. After cleaning an area for unrestricted access and use (or attempting unsuccessfully to do so) notify both the Reception Center Manager and the EOC Radiological Officer of the RM&D station status.
      h. After completion of monitoring and decontamination of individuals, ALL personnel working inside the Control Area will go to the Step-Off Pad area. Remove protective clothing and step onto the step-off pad to be monitored for contamination. All personnel who are contaminated MUST be directed to the personnel decontamination area.

    4. The Decontamination Workers are responsible for:
      a. Performing decontamination of vehicles and equipment.
 
III. GENERAL
 
  A. RM&D Station Objectives
The objectives of the Vehicle/Equipment RM&D Station operation are to:
 
    1. Identify contamination on vehicles and equipment arriving at the station.
    2. Decontaminate vehicles and equipment to less than the Action Level.
    3. Prepare records to document contamination which exceeds the Action Level (see Section VI. A.), decontamination procedures used, effectiveness of this decontamination, and the final disposition of vehicles and equipment.
    4. Minimize the spread of contamination.
 
  B. A generalized diagram of an RM&D station is shown in Attachment 5 Figure 1.
    1. Details for establishing each station are shown in Attachment 6.
    2. Details for establishing each Emergency Worker RM&D station are shown in Attachment 7.
 
IV. PRECAUTIONS AND LIMITATIONS
 
  Each Vehicle/Equipment RM&D Station worker shall observe the following precautions and limitations:
  A. Collect and secure for later disposal all solid waste that is potentially contaminated.
 
  B. Arrange the decontamination area so that uncontaminated vehicles and decontaminated vehicles do not pass through runoff water
 
  C. Use high pressure, low volume nozzles to minimize the amount of contaminated water.
 
  D. Minimized the spread of contamination by controlling contaminated runoff water to a small area and directing it into a storm drain.
 
  E. All personnel involved in decontamination will wear two (2) pairs of gloves, booties, tyvek coveralls and a face shield while washing a vehicle or equipment. Individuals performing only surveys may wear two (2) pair latex gloves, booties, and coveralls. Protective clothing will be placed plastic bags after it is removed and labeled for disposal. Protective clothing procedures are found in Attachment 4 Figures 7 and  8.
  F. Record contamination levels in units of CPM on the appropriate Vehicle Monitoring/Decontamination Form(s) (Figures 2-5).
 
  G. Keep clean plastic over the probe, and replace it if it gets contaminated. An indication of contamination on the probe cover is an increase in background level for no apparent reason.
 
  H. Report contamination levels which exceed the Action Level (see Section VI. A.) to the EOC Radiological Officer.
 
  I. For purposes of this procedure a “reading” is halfway between the low and the high indications when the probe is held stationary for 10 to 15 seconds. For example, if the low is 100 cpm and the high 200 cpm the reading is 150 cpm.
 
  J. Injuries to RM&D personnel will be handled according to Fictitious County Standard Operating Procedures for Emergency Medical Services In Support of the McGuire Nuclear Station. Notify the EOC Radiological Officer of any Illness or Injuries.
 
V. INSTRUMENTATION AND SUPPLIES

The instrumentation, equipment, and supplies necessary for RM&D station setup and operation are assembled into emergency kits. The contents of these kits are contained in Attachment 2. These kits are to be located at the Office of Emergency Management and are to be transported to the RM&D locations by the responsible fire departments or other designated personnel.
 

VI. ACCEPTANCE CRITERIA
 
  A. Action Level
    The term ACTION LEVEL in this procedure is the radiation level which separates “contaminated” from “uncontaminated.” The Action Level, measured with an E520 with pancake probe instrument is defined as follows:
    1. Action Level = 300 CPM
    2. If the background exceeds 300CPM, contact the EOC Radiological Officer for guidance.
 
VII. PROCEDURE
 
  A. RM&D Station Setup
    1. Set up the Vehicle/Equipment RM&D station as follows:
      a. Open and inspect the RM&D emergency kit at the fire station and report obviously damaged or missing items to the RM&D Officer
      b. Secure a low range self-reading (0-200 mR) dosimeter and a TLD badge, and initiate a Personal Exposure Record Card.
      c. Take the emergency kit and proceed to the designated RM&D location.
      d. Instruct and assist in clearing the area of all unnecessary vehicles and members of the public
      e. Establish the entrance, exit, decontamination, impoundment, holding, and monitoring areas using appropriate signs and barricades (see Attachment 5 Figure 1)
      f. Check the radiation detection instruments for operability as follows:
 
     

INSPECTOR EXP OPERATIONAL CHECK

      1) Remove survey meter from carrying case.  You must disconnect probe cable from meter before removal. 
      2) Install 9 volt battery (battery cover is located at the bottom on the back of instrument).
      3) Put survey meter back in carrying case and connect probe cable to meter and probe (make sure the connector is properly aligned before rotating connector latching mechanism).
      4) Turn survey meter On/Off/Audio switch to the AUDIO position and set the mode switch to CPM.
      5) Center probe face on check source on case. (Recommend holding probe in direct contact with check source pouch)
      6) Allow at least 30 seconds for reading to stabilize and record reading.
      7) The source reading should be within the range of (X)CPM and (Y)CPM as determined for that unit.
      8) If source check is OK, the meter is ready to use (go to step 9).  If source check does not fall within range readings, redo operational check by making sure the source is centered and allow 1 minute for stabilization.  If source check is out of the proper range reading do not use survey meter.
      9) Take a background reading in area where no contamination is present (if possible).  Allow meter reading to stabilize for at least 1 minute.  Record reading at the end of the 1 minute time period.  Multiply this reading times 5 and record for later reference.
      10) Cover probe with supplied plastic cover (do not use the RED plastic cover that is used to protect the pancake tube from physical damage).  Clear plastic kitchen wrap can be used to cover the probe or other thin plastic.  Secure plastic cover so that no part is hanging down from probe that would touch the area to be surveyed.  
       

(end procedure for instrument check)
 

  B. Vehicle/Equipment Monitoring
    1.

Refer to Attachment 5 Figure 1A as a guide for performing the following steps:

      a. Log, using Attachment 5 Figure 6, all vehicles and equipment arriving at the RM&D station for monitoring.
      b. Instruct the driver and passengers to remain with the vehicles/equipment until instructed further.
      c. Direct driver of vehicle to monitoring station inside the control (roped) area.
      d. Monitor should ask driver to release hood latch on the vehicle.
      e. Monitor should then open hood on vehicle, ensure that the shield of the probe is in the fully open position and covered with clean plastic. Survey the air intake by holding the probe about 1 inch away survey air intake filter. If  levels exceed the ACTION LEVEL, then place filter into disposable waste bag and close the hood.
      f. Check the exterior surfaces of the vehicle and/or equipment for contamination as follows:
      1) Ensure that the shield of the probe is removed and that the probe is covered with clean plastic. 
      2) Use the probe about 1 inch away, and slowly (not more than two [2] inches per second) and without touching  the surface move the probe while listening for an increase in the count (click) rate.       
      3) When contamination above background is suspected based on a noticeable increase in the count (click) rate, hold the probe stationary over the location for 10 to 15 seconds, and read the meter (halfway between the highest and lowest indications). 
      g. If contamination does not exceed the Action Level, direct the driver to exit the RM&D station(Skip steps h.-k)
      h. Monitor the interior of vehicle with particular attention given to the floors, pedals, seats and steering wheel. If         contamination on interior surfaces exceeds the Action Level, go to step C. 1. i.
 
        NOTE: If same individuals which performed exterior surveys do the interior surveys, the monitors should change gloves, shoe covers, and coveralls prior to beginning interior surveys.
 
     

i.

If contamination on interior surfaces does not exceed the Action Level:
      1) If the exterior is to be decontaminated promptly:
        (a) Instruct the driver to proceed to the Decon Area.
        (b) Decontaminate according to instructions in “ C” (Decontamination).
        (c )Re-monitor, and if contamination is less that the Action Level, complete the Decontamination Record, and direct the driver to exit the RM&D station. If contamination still exceeds the Action Level, go to Step “k”.
      2) If the vehicle is to be held for later decontamination of the exterior surface, go to Step “ j”.
 
      j. Instruct the driver to park the vehicle in the impoundment area, instruct individuals in the vehicle to go into reception center for registration, monitoring and decontamination.
      k. For vehicles with interior fixed contamination and/or vehicles with exterior fixed contamination notify RM&D Officer who will contact EOC Radiological Officer for instructions.
 
  C Decontamination:
Vehicle decontamination and re-monitoring should be performed only twice. However, if the vehicle/equipment is still contaminated and is considered to be essential, the decontamination and re-monitoring cycle may be repeated. If these subsequent decontamination attempts are unsuccessful, the RM&D Officer shall contact the EOC Radiological Officer for instructions.
 
    1. The general decontamination procedure is as follows:
      a. Instruct personnel to move vehicle to the decontamination area and remain in the vehicle.
      b. Wash the entire vehicle exterior including tires, grill, radiator, and fenders wells using a high pressure, low volume hose.
      c. Apply detergent, and scrub if necessary. Minimize runoff by using water only as necessary.
      d. If at all possible to prevent a repeat washing, decon worker should attempt decontamination using a clean cloth, and wiping over the contaminated area one time. NOTE: This will be useful on smooth surfaces such as windshields and fenders.
e. If the level remains above the ACTION LEVEL the cloth can be folded to a clean area, and the contaminated area wiped once again. The cloth should be placed in a plastic bag and tagged for disposal.
 
      f. If radiation levels cannot be reduced by wiping, direct vehicle back to the decontamination area for a second washing this time using a mild detergent and high pressure, low volume hose.
 
      g. If the radiation level still remains above the ACTION LEVEL, instruct driver to the Vehicle Impoundment Area. Notify RM&D Officer who will contact EOC Radiological Officer for instructions.
 
      h. After exterior decontamination is complete, the interior of the vehicles should be decontaminated if needed.
      i. If interior contamination levels are above ACTION LEVELS you should; wipe over contaminated area with a clean cloth for nonporous surfaces and repeat if necessary. For upholstery or other porous surfaces, decontaminate using vacuum cleaning with HEPA filter.
 
      j. Decontaminate tools and equipment using detergent and scrub if necessary. Wipe with a clean cloth. NOTE: The type of material deconed may require special methods. Notify the RM&D Officer who will contact the EOC Radiological Officer for instructions.
 
    2. After completion of monitoring and decontamination of vehicles, all individuals working inside the control area will go to the step-off pad area. Remove protective clothing and step onto the step-off pad to be monitored for contamination. All individuals who are contaminated must be directed to the personnel decontamination area. (See Protective Clothing Removal Attachment 4 Figure 8).
