1.0 PURPOSE The purpose of this procedure is to provide guidance to radiological and environmental monitoring teams for adequate onsite and offsite monitoring of radiation, contamination and airborne radioactivity levels, and environmental sample procurement, following the accidental release of radioactive materials to the environment. The procedure establishes monitoring team actions necessary to obtain data required to make valid radiological assessments.

2.0 APPLICABILITY/SCOPE All TMI Emergency Radiological and Environmental Monitoring Team Personnel.

3.0 DEFINITIONS 3.1 Derived Air Concentration (DAC) - The airborne concentration of radioactive material that if breathed by a worker for one hour, results in an estimated Internal Whole Body Dose (CEDE) of 2.5 mrem, or in the case of radioiodine, results in an estimated thyroid dose (CDE) of 25 rnrem.

3.2 External Whole Body Dose (DL)E) - The whole body dose from sources external to the body.

Typically this is the dose recorded on a whole body TLD. Official term: Deep Dose Equivalent.

3.3 Internal Whole Body Dose (CEDE) - The estimated risk-based dose to the whole body resulting from the intake of radioactive material. Official term: Committed Effective Dose Equivalent.

3.4 Thyroid Dose (CDE(th)) - the dose to the Thyroid resulting from the intake of radioactive material.

Official term: Committed Dose Equivalent - thyroid 3.5 Total Whole Body Dose (TEDE) - the sum of the External Whole Body Dose (DDE) and the Internal Whole Body Dose (CEDE).

4.0 RESPONSIBILITIES 4.1 The Radiological/Environmental Monitoring Teams are responsible for implementing this procedure.

5.0 PROCEDURE 5.1 Implementation Criteria 5.1.1 This procedure is to be initiated upon tha direction of the Emergency Director, the Radiological Assessment Coord;nator (RAC), the Environmental Assessment Coordinator (EAC), or their designee.

EXHIBIT I Page 1 of 2 Radiation Surveys To perform radiation surveys:

NOTE Sections A & B below should be implemented as needed based on direction from the RACIEAC. These sections can be repeated as needed.

A. Plume centerline scans:

1. General Guidance:

Scanning is most effective when the team slowly travels across the plume at approximately a 900 angle to the wind direction.

Scanning should be performed with a frisker or a survey instrument. If a survey instrument is used, the probe window should be open.

0 In inclement weather, the instrument probe should be covered with a surgeon's glove or plastic bag to keep it dry.

2. Ask the RAC/EAC to specify a start and stop point for scanning. If the RAC/EAC provides no direction, consult the map and choose a route which runs as nearly perpendicular as possible to the expected plume direction.

3 Proceed to the start point with the survey instrumentlfrisker turned on.

4 Scan by driving slowly (- 15 m.p.h.) while ho!ding the instrument probe outside the vehicle.

5. Locate the point where the instrument reading is highest.

5.1 Scan until the reading rises and then begins to decrease.

5.2 Reverse direction and return to the location where the maximum reading was obtained.

5.3 If the maximum readirg persists for a definite distance (i.e., a tenth mile or greater), find the approximate midpoint of that distance.

6. Report the plume centerline location and maximum reading to the RAC/EAC. When reporting the location, give any landmarks which may help fix your location on a map (e.g., intersections, public buildings, streams, etc.).
7. Perform a stationary survey as described below unless directed otherwise by the RAC/EAC.

Onsite/Offsite Radiological/Environmental Monitoring .9 px /

EXHIBIT I Page 2 of 2 B. Stationary Surveys:

1. Ensure the probe window is closed and hold.the instrument probe at waist level while standing outside the vehicle.

In inclement weather, the instrument probe should be covered with a surgeon's glove or plastic bag to keep it dry.

2. Obtain a reading by observing the instrument's needle for several seconds.

0 Mentally average the needle fluctuations to arrive at an average reading.

3. Obtain 3 readings per Step 2 above over a five minute period unless directed otherwise by the RACIEAC.
4. Record the following in Exhibit 5.

4.1 Record the 3 readings obtained per Step 3. If only 2 reading was taken, record it as "Reading 1".

4.2 If 3 readings were taken, average them and record the average.

4.3 Record the date, time and location of the reading(s).

5. Obtain one reading with the probe window open.

5.1 Record the reading (in rnR/hr) in Exhibit 5.

5. Report the location, time, average closed window reading and open window reading to the RAC/EAC.

EXHIBIT 2 Page 1 of 4 Radioiodine And Particulate Air Samples To perform air samples for Iodine and/or Particulate:

NOTE If possible, load the air sampler with the Silver Zeolite cartridge and particulate filter prior to entering the plume.

1. Unscrew the filter and cartridge holder rings from the air sampler head and install a new Silver Zeolite cartridge and particulate filter.

1.1 Ensure that the arrow on the side of the Silver Zeolite cartridge points toward the air sampler.

1 .2 Ensure that the particulate filter Is Installed such that the side of the filter which has a fibrous appearance is closest to the Silver Zeolite cartridge.

"1*.3 Reassemble the air sampler head.

NOTE The sampler flow rate, measure with both a particulate filter and a Silver Zeolite cartridge in place, is written on the air sampler's calibration sticker. The Silver Zeolite cartridge must be in place to ensure obtaining calibrated airflow rate even if an iodine sample has not been requested and the cartridge will not be analyzed in the field.

2. Ensure the following prerequisites and precautions are met:
  • The air sampler shall be placed outside the vehicle or in an open vehicle door or window.
  • Do not place the sampler on the ground or on known contaminated surfaces.
  • Keep the sampler away from vehicle exhaust gases.
  • Protect the sampler from rain and snow.
  • All samples shall be labeled and saved for further analysis.
  • Do not point the air sampler inlet toward any object which may restrict sampler air flow.
  • Do not stand directly in front of the sampler inlet when the samoler is running or allow loose clothing to restrict airflow.

Ž 40 < 46 Ipm ................................................. 7 m inutes S46 < 50 Ipm ................................................. 6 minutes NOTE The RAC/EAC or their designee may direct that sampler run time be shortened to reduce time spent in the plume or to reduce the "lead time" in obtaining sample results or lengthened to provide better sensitivity in low concentration areas.

4. Fill out an air sample label with date, time, your name, location, air sampler run time, and air sampler flow rate.

4 1 Also record this data on Exhibit 5.

5. To evaluate the Silver Zeolite cartridge in the field, perform the following steps:

5.1 Obtain a general area background count rate with the E140N/HP260 pancake probe at approximately waist level.

5.1.1 If the background is more than 200 cpm move to a location where background is acceptable (i.e. <*200) and proceed with Step 5.2.

5.1.2 If background is 200 cpm or less, go to Step 5.3.

NOTE If you Cannot find an area where background is < 200 cprn, ask the RAC/EAC for advice.

5.2 At the low background area run the air sampler for approximately 3 seconds to flush the cartridge.

4 REM Year-to-Date Total Whole Body Dose (TEDE).

25 REM Thyroid Dose ýCDE) during this event.

whole body A rough approximation of the iodine derived air concentration (DAC), thyroid dose (CDE) and internal dose (CEDE) can be obtained using the following relationship:

Every 1000 net cpm on the silver zeolite cartridge equals roughly:

20 DAC Iodine, 500 mREM/hr Thyroid Dose (CDE) and 15 mREM/hr Internal Whole Body Dose (CEDE)

For example: 5000 net cpm on the cartridge would roughly equal: 100 DAC Iodine, 2500 mREM/hr CDE and 75 mRERM/hr CEDE.

NOTE

1. This information is intended for field team use only and not for making dose projections for the public.
2. The relationships shown above are valid only if the sampler run times specified in the sampling instructions are foltowed.
3. The relationships are based on conservative assumptions (e.g. all Iodine is 1131) and will in most cases overestimate the field team's dose. More refined estimates can be obtained from the RAC or EAC.

EXHIBIT 9 Page 2 of 2 HOW POTASSIUM IODIDE WORKS Certain forms of iodine help your thyroid gland work right. Most people get the iodine they need from foods, like iodized salt or fish. The thyroid can "store" or hold only a certain amount of iodine.

In a radiation emergency, radioactive iodine may be released in the air. This material may be breathed or swallowed. It may enter the thyroid gland and damage it. The damage would probably not show itself for years.

Children are most likely to have thyroid damage.

If you take potassium iodide, it will fill-up your thyroid gland with non-radioactive iodine. This reduces the chance that radioactive iodine will enter the thyroid gland.

WHO SHOULD NOT TAKE POTASSIUM IODIDE The only people who should not take potassium iodide are people who know they are allergic to iodide. You may take potassium iodide even if you are taking medicines for a thyroid problem (for example, a thyroid hormone or anti-thyroid drug). Pregnant and nursing women and babies and children may also take this drug.

HOW AND WHEN TO TAKE POTASSIUM IODIDE Potassium Iodide should be taken as soon as possible after proper authorization is received. You should take one dose every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. More will not help you because the thyroid can "hold" only limited amounts of iodine.

Larger doses will increase the risk of side effects. You will probably be told not to take the drug for more than 10 days.

Contact company medical personnel to determine how long you should take potassium iodine.

SIDE EFFECTS Usually, side effects of potassium iodide happen when people take higher doses for a long time. You should be careful not to take more than the recommended dose or take it for longer than you are to!d. Side effects are unlikely because of the low drug dose and the short time you will be taking the drug.

Possible side effects include skin rashes, swelling of the salivary glands, and "iodism" (metallic taste, burning mouth and throat, sore teeth and gums, symptoms of a head cold, and sometimes stomach upset and diarrhea).

A few people could have an allergic reaction with more serious symptoms. These could be fever and joint pains, or swelling of parts of the face and body at times severe shortness of breath requiring immediate medical attention.

Taking iodide may rarely cause overactivity of the thyroid gland, underactivity of the thyroid gland, or enlargement 0f the thyroid gland (goiter).

WHAT TO DO IF SIDE EFFECTS OCCUR If the side effects are severe or if you have an allergic reaction, stop taking potassium iodide and contact the medical department.

EXHIBIT 10 Page 1 of 2 Field Team Radio Operating Guidelines NOTE The following sections provide guidance for operation of the field team portable radios. Individual sections can be implemented as needed.

To operate the portable radio:

A. Turn on the portable radio by rotating the "power on-off/volume" knob clockwise. The radio will perform a "power up self test" and then display:

Its unit number (e.g., "TMI P 1l is portable radio #1) and Either "EARS" or "CC SCAN" depending on whether the radio is receiving the system Control Channel signal (i.e., if "CC SCAN" appears, the radio is out of range or in a bad location).

B. To transmit:

Make sure that "EARS" is displayed on the front of the radio and then press the Push-To Talk (PTT) button (elongated button on the left side of the radio).

  • When the short medium pitch beep is heard, begin speaking.
  • If a high pitch beep is heard when the PTT is pressed, the system is temporarily busy.

Don't release the PTT button - continue pressing it and wait for the short medium pitch peep before starting to speak. The delay should typically be not more than a few seconds.

When speaking, hold the radio approximately 3 inches from the mouth and speak in a normal voice.

C. Receiving:

When a call is being received the calling station's identity is displayed in the upper line of the radio's display.

EXHIBIT 10 Page 2 of 2 D. System status beeps:

The radio will indicate system status by emitting any of several beeps:

A short medium pitch beep indicates that the radio has begun to transmit and the user may begin speaking.

A high pitch beep indicates that all system channels are busy and the radio is waiting forthe next available channel. The user should continue pressing the PTT button until a short medium pitch beep is heard and then begin speakin.

If five short high pitch beeps are heard while transmitting, this indicates that the radio is approaching its 60 second transmission length limit. Unless the radio is un-keyed before the long low pitch beep is heard, the radio will stop transmitting and information will be missed. Long transmissions should be broken into several shorter transmissions to avoid this.

A low pitch beep simultaneous with the appearance of a battery icon in the lower right corner of the display indicates that the battery voltage is low and the battery should be changed.

E. To replace the battery pack:

Turn the radio off.

Depress the recessed button beside the belt clip on the rear of the radio and slide the battery toward the bottom of the radio.

  • Lift the battery up and away from the radio.
  • To install a fresh battery pack: Align the tabs on the battery with the slots on the radio and slide the battery pack toward the top of the radio until it dicks.

F. The channel selector knob and the buttons on the front panel of the radio serve no function and should not be manipulated.
