SAMPLES AND ANALYSES Thermoluminescent Dosimeters fi'LDs)

One, of a possible 180 TLD samples, was missing during 1996 due to vandalism. The missing TLD occurred:

Third Quarter - TLD 76 was missing in the field.

I ANALYTICAL PROCEDURES Gross Heta l Gross beta radioactivity measurements are made utilizing a Tennelec Low-Hackground i Alpha / Beta Counting System. The LLD for air particulates is approximately 3.0 E-3 pCi/m'.

l l

Air particulate samples are mounted in 2 inch stainless steel planchets and counted directly for 50 minutes.

i Tritium

~

j Liquid samples requiring tritium analysis are treated with a small amount of sodium hydroxide and potassium permanganate crystals and then distilled. Five milliliters of the distillate are mixed with thirteen milliliters of liquid scintillation cocktail and counted in a liquid scintillation counter for 50 minutes. The LLD for this count time was apprordmately 1000 pCi/L through May 1996. During June 1996, the sample count time was incr.:ased to 500 minutes with a LLD of approximately 325 pCi/L This increase was established to compare our tritium LLDs and results with State Agency's reportable concentrations, in the Split Sample Program's Annual Report, as per plants' request.

Indine-131 Jodine-131 airborne concentrations are analyzed by the intrinsic germanium (Ge) gamma spectrometry systems. The cartridges are placed on the detector and each charcoal cartridge is counted individually with an approximate LLD of 3.0E-2 pCi/m'.

Samma Spectrometry

= Gamma spectrum analysis utilizes intrinsic germanium detectors with thin aluminum windows housed in steel and lead shields. The analyzer system is the Canberra Nuclear 9900 Gamma 34 8-27-97  !
