RESULTS AND COMPARATIVE ANALYSIS
5.1
RESULTS
EXTERNAL DOSE
The gammaradiation 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.
Personne! 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 personnel doses..
Average doses to the
identifiable subgroups of Rongerik personnel are as follows:

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.
