“able 4, Alpha Emitting Nuclides *n Soil - Eneman (pCi/g air-dried weight) nuclide 29, 240 100 uR/rr area PU 2285 e+], 500 uk/hr area 24 Alo 1] 220 2 40 UNCLE (ENIDRIK) yhe island of Enidrik is located west of Eneman on the southern rim of the atoll (Figure 8). The northwest end of the island is heavily vegetated and showed background radiation levels of 100 to 300 uR/hr over most of the area. The central portion of the island consists of coral rubble overgrown by jpomoea vines and the background radiation levels are generally 19 uR/hr or tess. Progressing toward the narrow eastern end of the 1stand the vegetative cover remains thin. Two large sandy areas, cevoid of vegetation, dominate this end. Background levels remain at 10 wR/hr or less over the great majority of the eastern end. No coconut trees were found on the island. A few scattered mature pandanus were seen, and one small grove of immature pandanus was located on the western end. One arrowroot sample was taken at tnis last location where the background was 250 uR/hr. The ‘'42’Cs concentra- tion in the arrowroot was 0.2 pCi/g (wet weight) after processing as previously described. A soil sample taken in a 300 uR/hr area showed 102Mp,° 137¢5, and ©Co to be the major gamma emitting contaminants (78%, 14%, and 8% respectively by concentration). Only a few pieces of radioactive debris were found and these were renoved for burtal at sea. V7? gums 309039
