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 personnel doses.

Average doses to the

identifiable subgroups of Rongerik personne! are as follows:
