PRECAUTIONS. AND Lil!ITATIONS Sampling locations and. frequencies will be determined by the Site.Emergency**
Direc.t.or depending on environmental conditions and population distriqud.ons.
Suggested locations are. indicated on Figµre l~.
s*ampling *may take place* in: highly contaminated areas.:..
Anti-c~ntamin~tion
- clothing and respirators may* be needed under these conditions.

Place particulate pre-filter ~n place to prevent buildup of radioactive particulates on cartridge.
Screw on retaining r~ng and attach sample head
.to air sampler.
. Turn on sampler and adjust air flow to 1. 0-2. 0 cfm.
Note initial air flow reading and time.when sample collection started.
A ten (10) minute sample should be taken.
At the end of 10-minute sample period, note airflow reading and time and turn off sampler.
Remove cartridge frc.m sample head and place cartridge in polyethylene ba~.

Analysis Take carfridge to* low background ar.ea or use lead bricks to shield pr9b~ if background radiation levels exceed 300 c?m
- Place:- probe: in contact with side away from arrow on cartridge.. Note reading on rate meter after meter has-stabilized*.:.
If range of meter is exceeded, repeat air sample (section 5.1) but decrease sample time. to aEpro,..."i.mately one-half. af.. previous. sample time.**
Cal~ul~te ~irborne iodin~ concentrations using the following equation:.
C =. (G. 7E-ll) (Rs-Rb) ts 1/2 (F1+Fz)
Where:
C = Concentration (uCi/cm3)
Rs = sample count rate (cpm)
.,. ~ = background count rate (cpm).
Fi = initial flow rate (cfm)
F2 = final flow rate (cfm) ts = elapsed sample time (minutes)
