C c Figure Captions Fig. 1. Map of Bikini Atoll. Fig. 2. The geographical variability of the gamma-ray exposure rates (uR/hr) measured lm above the ground on Bikini Island. Unfortunately, the exposure rate con- tours shown in this photograph to delineate areas having different contamination levels are not clearly visible in this black and white reproduction of the original color photograph. The straight lines drawn across the island denote boundaries of land parcels (watos) owned by the families whose names appear in the upper part of the photograph. The numbers in the lower part of the photo denote the number of bouses within each wato that are planned as part of Phase II (upper number) and Phase III (lower number) construction plans. Fig. 3. The geographical variability of the gamma-ray exposure rates (uR/hr) measured 1 m above the ground on Eneu Island. Fig. 4. A map of Bikini Island showing specific areas of interest for the dose calculations. Existing houses are situated within area 1. Areas 2 and 3 are proposed village sites for future housing units. The interior portion of the island is denoted by area 4, -1i-
