Scove: (a) 200 Word Summary: A comprehensive external radiacion survey program will be conducted on each of the approximacely 13 arslls or islands in the Northern Marshall Islands which could have received tropospheric fallout from U.S. muclear weapons cests in the Pacific. The surveys will provide "ground truch’ daca on ambient external gamma radiation levels on-island. This daca will be used as the dSasis for calibracion and normalization of aerial radioiogical monitoring by £.G.&G. Corporation. The program will include detailed extermal radiation measurements with voressurization chamber and scintillation survey instruments, and in situ zamma spectrometry on all islands of interesc. Surface soil samples will be collected and analyzed for significance gamma amictars in order to make decay corrections for long-term dosa sredictions via tne external radiation exposure oathway. BNL field trip start and analytical lab facilities will be avatiaole for other environmental sample collections and analyses as needed dv the overall gciencific program. 15. Relarionshis to Other Projects: This program is direcely related to our comtinuing envircnmencal and per- sonnel monitoring efforts under the 3NL Marshall Islands Radiological Satety ay Program. Le will also interact cooperatively with related efiorts ac che University of Washington (LRE) and Lawrence Livermore Laboratory. te \ Extarmal Radiation Measurements and "Ground Trutn’ for Northera Marshall Islands Regional Radiological Survev . 7 Technical Progress in FY 1973: Personnel and analytical laboratory resources will be mobilized in support of this program. If the regional survey begins on schedule, the first or the three survey legs should be completed by the end or FY 1978. + Ly. «Expected Results in FY 1979: The remaining two survey legs will be completed, data analyzed, and a (See Continuacion Sheet)
