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 possible 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. Table 3. Comparison of calculated film badge doses with dosimetry.

That these ratios are similar under varying circumstances of exposure suggests that there is a systematic overestimation of dose in the foregoing analysis. The 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 | are reduced by a factor of I.1 in order to be consistent with the dosimetry results. This adjustment in the Table | doses yields the best estimates of film badge doses received by the personnel on Rongerik. Such an approach provides the most consistency when the exposures are characterized by a mix of film badge readings and calculated doses. Results are presented in Section 5. 15
