OO—————— smaller portion (less than 10%) of the estimated whole-body, bone-marrow, or effective dose. The '37Cs body burdens of the Bikinians were determined by whole-body counting prior to their relocation in August 1978 (Miltenberger et al., 1980) and were within the range we estimated based upon our measurements and our diet model (Robison et al., 1982b). SAMPLE COLLECTION AND PROCESSING PROCEDURES Qur sampling and processing procedures have been described in some detail in Robison et al. (1982a, 1982b). Briefly, soil samples were collected as soil profiles with the following increments of soil depth: 0 to 5 cm, 5 to 10 cm, 10 to 15 cm, 15 to 25 cm, 25 to 40 cm, 40 to 60 cm, and 60 to 100 cm. Soils were oven dried at LLNL, screened through 1/8" mesh, ball-milled to a fine powder mixture, packed in- aluminum cans, and analyzed for !3/Cs by gamma spectroscopy. The samples taken during the 1978 survey were subsequently sent for analysis of 29Sr, 239+240py, and 247am by wet chemistry. Wet chemistry analyses from our Bikini and Eneu Island continuing program were somewhat limited due to budget constraints, and approximately 40% of the soil samples taken were sent for analysis of 20Sr, 239+240py and 24!am by wet chemistry. Edible food crops such as coconuts, breadfruit, and Pandanus fruit were collected where they were available. Most food crops were unavailable at islands other than Bikini and Eneu, the exceptions were coconut samples on both Jelete and Aerokojlol. Vegetation samples, including food crops, were frozen in the field and shipped frozen to Lawrence Livermore National Laboratory (LLNL), where they were reduced to constant dry weight by freeze drying, ground to small particle size, packed in aluminum cans 8.0 cm in diameter by 4.6 cm deep, and analyzed for !3/Cs by gamma spectroscopy... After gamma spectroscopy, approximately 12% of the canned samples were sent to an analytical laboratory for analysis of 90Sr, 239+240py, and 241Am by wet chemistry procedures. Muscle tissue and organs from pigs and whole chickens slaughtered on the islands were frozen and transported to LLNL. to the food-crop samples. J000312 Samples were processed similarly
