This reports concentrates on the resules of the environmental monitorin program. The external dose measurements with the use of ion chamber and field gamma specettoscooy will be reported separarely as will dose commicamenc estimates via various ineernal exposure pachways. Bikini Acoil Environmental surveillance of Bikini Acoll was achieved by sampiing vegetation, soil, fish, cacchmene water and sediment. Eneu Island was surveyed for external radiation and sampled for marine fauna, soil and vegetation consisting of Scaveola leaves, Messerschmidia leaves , coconuts and pandanus. Eneu nad previously been idencified as a potential village island, since it received che lease amount of radioactive falloue during the atomic bemo testing. EIneu has also been suggested as the main source of food produccion for shese indivi- duals living on 3ixini Island (2,1). Consequentiy, thorough sampling of this island was essential to establish radionuclide quantities wishin the food chain. The island of Nam was considered to be heavily contaminated because of its stoximizy co the 1954 3RAVO evenc. Eavirommencal monitoring to dare on this island includes samples of muilee and snapper fish, six inch soil cores and soil oroftiles, scaveola and nesserschmidia leaves. Several food {rems grown on Bikini Island have been suggested for exclusion from che local diet (2,2). Samples of coconuts, pandanus, breadfruic, atrowroot, scaveola leaves, messerschmaidia leaves, sumpkins, squash, bananas and papaya, soil samoles in the form of 15 cm cores ard 0-100 cm soil profiles, mackerel (fish) and cridacna (clams), plus caechment sediment and wacer have Seen collected in an effort co decermine cheir radiological impacts as local marine and cerrestrial food items.
