Rene ee le ee -3- The foreed change in diet has contributed markedly to their inebility to edept tm Kili Islemdi. Thus the stromg desire on the part of meny to retura to their astive Bikini Atoll remains slive. There are now approximately | 500 peaple om Kili Island end when @ poll wes teken early in 1967, 145 of the gramps indicated ae desire to return to Bikini Atoll. Za: the ten years which elapsed frou the lest test series (1958) st = Bikial Go the present, the stoll has been essentially aninhabited. Dense vegetution hes spreed over the larger islands, and native marine end | terrestrial animals have flourished in men's absence. Dering the period from 1946 to 1958 the lend mess end veter ia the | lagows #t Bikini Atoll became conteninated from both atmospheric and underwater ‘tests. Brief rediclogical surveys were mede on several occasions to follaw the decay of redicectivity on the etoll; however, an intensive, rether complete rediological survey ves mede during August 1964. ‘The decision was wade @tthst time that the health and safety of pecrle returning perneneatly to the eres might be endangered. A detailed resurvey vas made during April- may 1957. Br. Guetafson reported thet the rediological resurvey of Bikini Atoll comsimted of teking numerous rediation ex: osure measurements, and collecting reyresentative semples of the ;roninent plant end snisal species (including fish aad birds). Perticular efforts were made to sample those iteas likely to be: eonsumed as food by the returning Bikinians. Severel kinds of devices were amped to meesure redietion dose rate. Confirmation of dose rete by more then coe instrument increased relisbility, end the field Yoray spectrometry provided detailed imformetion om the redicauclide composition of the ecatenination. es ry ye ty \ Poy he : , Ry 2 OL ~de a fog ie had “4 ~ aia . eel5377 whe : a: ~ ; . . 397 “Te -
