ENIWETOK RADIOLOGICAL SURVEY SAMPLE ANALYSIS PROGRAM PROGRESS REPORT MARCH 2, 1973 This is the first periodic report of the analysis phase of the Eniwetok Radiological Survey. This phase is expected to extend over the next five-six months, during which time these monthly status reports will be made. Attached is a graphical representation of analysis progress. each type of sample has three major steps: and digitizing, and chemical analysis. Generally, preparation, gamma counting Sample preparation consists of drying, grinding, homogenizing, tagging, and packaging to send off toa laboratory for actual analysis. Before they are sent to the various labs, gamma counts are made and data for each sample is entered in the computer bank in the Biomedical Division, LLL. then made at one of the following five labs: Chemical analysis is LLL, University of Washington, McClellan Central Laboratory, LFE Environmental Analysis Laboratory (formerly Trapelo), and Fberline Instrument Corporation. Seawater samples are chemically processed directly by LLL, so consequently the preparation and gamma counting bars are not shown onthe graph. Below each type sample on the graph is indicated the total number of samples gathered during field operations. fish samples to be analyzed. Attachment: As stated above For example, there are 456
