PERSONNEL EXPOSURES

It is because this estimate for this large group

Given that Table 25 is a fair estimate of the BRAVO contr§gbution to
the collective exposure from the CASTLE series, then this can]be subtracted
from the whole-series data from the Consolidated List
(Reference 13)

Taking the

with the TG 7.3 total from Table 59 shows about the same relationship.
Fortunately, there were no non-task-force exposures for the laker events
that were comparable to those represented by the non-JTF 7 exppsure statistics in the rest of Table 25.
