Scope: (To de aritecn by principal investipato: -approsimacely 80 words) - The laboratory has collected marine, terrestrial, and soil samples for radiological analyses at the former Pacific Test Site since 1946 and some of these samples have been prepared and stored for later use. A list of samples by date and area of collection and by semple type that are now on hand iS given in the five tables that are attached. Reports of tne results of analyses of most of the samples have been reported but all of the methods and techniques of analyses that are now available were not available when the samples were originally analyzed. For example, prior to 1954 the only analysis performed was for gross beta and ganma radiation; the analyses for FG began in 1954 ana, by gamna spectrometry, in 1956; and, for plutonium, the first analysis Wag in 1965. It iS now proposed that selected archive samples be analyzed for Ose, Cs, and Pu for the baseline program for FY's 79 and 80. As a result of this program, the 3l-ycar history of these radionuclides at Bikini and Enewetak, their 24-year history at Rongelap, and their 20-year history at these three areas, as well as other areas, after conclusion of the test program could be established. It is unlikely that similar infarmation can be obtained for any other area of the world. The number of analyses will be approximatey 206 for Pu, 200 for 905). | 200 by gpa spectroscopy (V37¢Cs and other radionuclides if present) and 20 (of the more | recent fish samples) for ~~Fe per year. in FY 1976, the analyses of all of the samples collected in 1976 and 1977 for DOLS that have not beer previously analyzed will be completed. The results of analyses will be included in twa reports - one, on the Ve?G radiological survey in ticronesia and the other on 1976 and 1977 radiological surveys in the Marsal Islands. The latter, essentially, will be an updating ef NVO-269- 32, =ee — Bos. CAGE: ~ ee
