TO: W. E. Nervik, Division Leader, Radiochemistry status as of 23 number 2, Eniwetok sample analytical programj summarizes the laboratory analytical effort being carried on at LLL by members of the Ruliochemistry Division, Biomedical Division, and Hazards Control Department, at the University of’Washington and at Eberline Instrument Corporation (Dr. Eric Geiger, Mr. Ernest Sanchez). and sediment samples (estimate 2500 samples to be processed): or completed, as of 23 Feb. ’73: 1,325 as of 9 Feb. ’73: 1,050 C!urrentrate: a 100 samples per week. samples (456 samples to be processed): Initial processing (UW, Seattle) - following list of ssaqles prepared, shipped, and received at LLL as of 23 Feb. *’73: 431 fish, other aquatic animals Initial processing phase complete as of 23 Feb. ’73.

Chemical analyses, ssmples dissolved and elements isolated chemically: in 166 soil and sediment samples (9 26 Feb. t73. Analysis of 55 soil Feb.~73, Plan to deliver second samples began on batch of 50 samples They have reported 90sr and 239m data on 6 ~ualifi cation ssmples. In addition, they have analyzed a second se~ of 6 qualification samples and have reported 239fi data . This last set of data showed a systematic bias of 25%. A standard solution of pure 239 +24o Pu has been shipped to EIC for calibration purposes. We expect standardization of their tracer solution with the standard 239Pu will eliminate the bias. Samples of this standard solution will also be shipped to MCL, LFE, and UW for interlab calibration. Analysis of a set of 12 selected samples for 239PU will be compared to assure accurate calibration of
