2. On-Site Analysis. geometry for The samples are then transferred to an approximate 700 ¢ gamma counting for 24lAm, 152—u, 155Eu, 137Cs and OK. After gamma counting has been completed, the samples are split. One portion shipped to EIC, Albuquerque Laboratory, and the other portion stored in the Soil Library. The shipping box will have a packing list with EIC Laboratory number and hard copy of gamma results with island location information. On-site gamma sensitivity for 187Cs will be approximately 1 pCi/g. Pu/Am chemical analysis will be done on island as laboratory load permits working to the goal of chemical analysis of 10% of all 100-meter samples. The sample locations to be processed for Pu/Am will be specified by the DOE/ERSP representative. Off-Site Analysis. EIC offsite analysis will include processing coral sample for 90sr and all other Pu/Am not completed on Enewetak. DOE/ERSP Procedure No. 15 assumes secular equilibrium of 90sr and 99Y has been attained. The 90y is separated and used to quantify the 90sr, Americium and plutonium analyses offsite include isolation of plutonium from americium and electrodeposition. Tracers will be used to quantify plutonium and americium activity based on the ratio of the tracer to isotope of interest. A-28-3
