for a specific badge, the exposure of the film badge during the period it was in the
mess hall (H+28.75 to H+35.25) must be added to the calculated film badge dose as of

H+28.75 hours. This "mess hall dose" is approximately 12 rem.
From the personnel interviews it is possible to calculate the H+28.75 film badge

dose for two of the film badges whose readings are given in Table 2 (badge #311 and
#312). In addition, it is passible to calculate the H+28.75 hour dose for the badge that
was hung on the tent post in the Army area (badge #314).

Table 3 compares the

calculated film badge dose at H+35.25 hours (the calculated dose at H+28.75 hours plus
the "mess hall dose") and the corresponding film badge reading (from Table 2) for these
three film badges. The activity scenarios or protection factors pertinent to the other
badges are insufficiently known to permit meaningful comparisons.

From Table 3, the calculated dose to a specific film badge at H+35.25 hours is

approximately

10-14 percent higher than the actual film badge reading.

This

difference between the calculated doses and the film badge readings could easily be
accounted for in the uncertainties associated with defining the free-field radiation
environment and protection factors on Rongerik. Thus, the estimated doses in Table |
fare conservatively reduced by 10 percent in order'to be consistent with the dosimetry
results. This adjustment in the Table 1] doses yields the best estimates of film badge
doses received by the personne! on Rongerik. Results are presented in Section 5.
