SECTION 5 RESULTS AND COMPARATIVE ANALYSIS 5.1 RESULTS EXTERNAL DOSE The gamma radiation dose to the servicemen on Rongerik Atoll is reconstructed as follows. The radiological environment resulting from Shot Bravo fallout is determined from time-of-arrival data on Rongerik, modeled deposition, measured decay rates, and a late reading on Rongerik. Personnel activity scenarios are considered in conjunction with radiation shielding factors to arrive at film badge doses on an individual basis. Although film badge readings are available, they inadequately relate to personnel dose. Readings that reflect well-specified exposures indicate good agreement with corresponding calculated doses. A small, but systematic, difference indicates an adjustment to the calculated personne! doses. Average doses to the identifiable subgroups of Rongerik personnel are as follows: Group First Evacuation Number of People g Average Dose (rem) 33 “ " Second Evacuation Air Force Army 17 38 ° 3 43 ° Reconstructed doses are presented by case number in Table 4, with individua! scenario information included as available, INTERNAL DOSE Organ-specific 50-year dose commitments resulting from the large-particle inhalation and ingestion of Bravo fallout radionuclides are given in Table 5. 23 The
