Eniwetok sample analytical prcgram. Progress Report No. 3. This progress report summarizes being carried on at LLL by members of medical Division, and Hazards Control the laboratory analytical effort the Radiochemistry Division, BioDepartment, at the University of Washington (Dr. Allyn Seymour, Dr. Victor Nelson), at McClellan Laboratory Mr. William Major), and at Eberline Instrment Corporation (Mr. Eric Geiger, and sediment samples (estimate 28OO samples to be processed): or completed, as of 9 March 1973 - 1~6J+0 as of 23 February 1973 - 1,325 as of 9 February 1.973 - 1,050 Current rate: 2 125 samples per week. samples (441 samples to be processed): Final breakdown on samples prepared at UW, Seattle and delivered to ILL for gama counting.

Core samples (36 samples collected): Total of 36 collected. In various stages of processing at LLL. These are being sectioned into 5-cm slices, dried, ground, and analyzed. A total of 165 samples will result from 36 cores. Air filters (61 samples collected): Remainder will be processed as soon as results are in on Gamma counting, precision Ge(Li) detector spectroscopy:

Samples counted and data in computer bank (LLL) - * There are 50-100 samples where counting results have been obtained but are not into the data bank due to slowness in processing in the big computers. These .till appear in the Chemical analyses, samples dissolved and elements isolated chemically: Data on 9°Sr or Pu LFE Environmental Analysis Laboratory Contract finally ccmplete * 2 March 1973. Chemical analysis of coral samples for 9oSr and 239Pu began on 5 March 1973. A total of 108 samples have been deiivered to LFE as of 9 March 1973.,
