a<u wvu1 SITES 1.
Activation of Environs Group Teams.
2.
Each team should be equipped with or have access to necessary samoling equipment.
3.
Each team member should be properly trained in the use of the sanpling equitunent and be familiar with all the apolicable procedures.
4.
We Environs Groups uMer the supervision of the Rad / Chem or Environs Director will consist of personnel from CECO and contractors designated to assist the groups.
D.
PPECM7"Iots 1.
When entering an area where unknown types and concentrations of airborne radioactive material exist, the Environs Director shall direct what type of resoirator/
protection is needed and if protective clothing shall be worn, as the situation warrants (per EG-4).
2.
Only calibrated instruments and air samoling equipment shall be used. Equignent should be tested before use, and if it rescoMs incorrectly, the Environs Director should be notified and the instrument replaced with a workiry model.
3.
Each sample shall be properly labeled as acolicable with the date, time, location, flow rate, flow time, samole taker's name and/or any other information pertinent to sample analysis included.
4.
When noble gases are suspected to be present, cernoletely bag and seal the C.P. in a plastic bag.
5.
When taking Window Open (WO) and Window Closed (WC) readinas with the C.P. end wiMow pointed towards the ground at heights of 6 inches and 6 feet above the ground:

EG-3 Revision 2 Januar/,1982 D.
PRECALTICNS (Continued...)
l 5.
a.
If the beta /gama readirns at 6 feet are significantly less than the 6 inch readings, then it is probable that the team is not submerged in the plume and is measuring predominately beta /gama contamination from the ground. Therefore, the gama a
radiation measurement at 6 inches is acpropriate to determine the wholebody exposure rate.
b.
If the beta /gama readings at 6 feet are greater than the 6 inch readings, then it is probable that the team is subnerged in the plume and is measuring predominately beta /gama radiation from the plume.
However, these C.P. readings are not representative of the beta / gamma dose rate from the plume unless the C.P. is comoletely sealed fro' the entr/ of noble gases into the chamber.
c.
If the beta /gama readings at 6 inches and 6 feet above the ground indicate no beta radiation is present (ie. WO and IC readings are the same), then the team is not subnerged in the plume and is measuring predaninately gama radiation from the neartr/ plume, not ground contamination. Therefore, the gama radiation measurement at 6 feet is aporopriate to use when determining the wholebody exposure rate.
E.
LIMITATIONS AFD ACIICt3 1.
An inventory and inspection will be performed on a cuarterly basis and after each use as required by each Station's procedures to ensure the operational readiness of the Environs Sampling Kits.
2.
Verify that the equignent and supplies listed in Attachment A are present and/or cperable. If items are missing, not in adequate suoply or inoperable ensure corrective action is taken to clear the deficiency.
3.
Calibrate all instruments in the Environs Samling Kit at least ever/ six months.
4.
Film badgas or TID's will be individually sealed in plastic with a desiccant and replaced semi-annually.
5.
Ensure all dosimeters are quality control tested every six months in accordance with each station's procedures.
6.
Replace all spare batteries in the Environs Sanpling Kit annually.
7.
The Environs Sampling Kit inventory should be reviewed by a member of the Stations' health physics staff after it has been comoleted.

LIMI"'ATIO?S AND ACTIONS (Continued...)
8.
Initiation of environmental sampling activities and direction -f the Environs Groups will be performe< by the Rad / Gem Director until the Environs Director has been notified and assumes his duties.
9.
If the radiation levels at the site boundary are significantly elevated, initial emphasis should be placed on detecnination of offsite radiation levels and identification of areas that require controlled access and or evacuation.
10.
If the areas have a significantly elevated radiation level, entry shall be at the discretion of the Environs Director. Appropriate clothing and respiratory protection shall then be issued. (Ref. EG-4)
F.
PnOCEDUPE 1.
Determination of Ground Contamination The following metnod can be used to quickly determine if there is significant ground contamination. Surface contamination exists when the level of contamination exceeds 100 c:m/ft2 beta-ganna or 500 dpm/ft2 alpha above backcround, as measured by a portable survey instrument (e.g. Geiger-Mueller). Using a GM instrument take a reading at approximately 3 ft. above the ground.
Take a second reading at six inches above the ground.
If the 6" in reading is significantly higher than the reading taken at 3 ft., ground contamination is present. Record both results in the sanpling log and note the location (s) of ground contamination. Contact the Environs Director with this information.
2.
Verifvino Exoosure Rate Patterns The well defined plume under stable conditions represents the greatest hazard at the farthest distance from the site. Additionally, under extremely stable conditions, elevated and continuous releases will have such little dispersion that ground level measurements may not be in the plume even at distances of a mile or more from the point of release. The sampling imations should therefore be adjusted according to plume stability. 'Ite more stable the plume, the farther out they will need to be.
a.
Use the following methods to verify the patterns of the estimated exoosure rates frcm an airborne release:
(1)
At each measurement location take readings in both the open and closed window positions.
(2)
Measure at a few points close to the station (the E virons Director will select the points) using a C.P. to determine the center-line exoosure rate and extracolate dowT1 wind, taking Pasquill conditions into account.

EG-3 Revision 2 January, 1982 l
F.
PDOCEWRE (Continued)
(3)
Measure radiation levels across the plume at two or more distances downwind of the station, usirg a C.P. (high range if.acessary) and measure the maximum levels at the plume center line.
(4)
Measure at points in a pre-planned grid pattern that is centered over the dowrr.<ind line relative to the station.
(5)
For a release of long duration, a projected pattern may need to be revised whenever there are significant charges in the meteorological conditions, release rates or release conoosites.
D.
Instrumentation Recuirements (1)
Use the instrumentation package to verify plume projected dose by taking both direct gama measurements of the plume ard a five minute air samole.
(2)
Average the reading obtained over a 30 second time span at approximately 3 feet (1 meter) above the ground and also acoroximately 6 in, above the ground at the same location. Record readings.
(3)
If the 6 in, readir.g is lower than the 1 m reading assume the predominate gama source is the airborne plume. If the opoosite occurres, i.e. the 1 m reading is lower than the 6 in. reading, assume most of the gamma source is deposited on the ground.
3.
Air Samolire 3 is a.
Run the air sampler for 5 min. or until 30 ft reached. Remove the particulate filter from the canister and measure the gama exposure rate from both the canister and filter. Subtract the direct (collected at Im) gama measurement from both the canister and particulate filter measurements. If the gama reading is more than 10% of the readings obtained from the samole media reevaluate the canister in a lower background area.
6.
Obtain and replace particulate and iodine saneles from the Fixed Environmental Monitoring Stations.
Work initially in downwind areas. Forward samples to a laboratory designated by the Environs Director for analytical counting or to the station itself.
