The NTPR teams have accomplished most of their original goals. As their work is completed, remaining responsibilities will be consolidated at DNA beginning in fiscal year 1987. 1.5 SUMMARY OF RADIATION DOSES. Doses to participants at the atmospheric nuclear tests have been determined through several means. Film badge dosimetry, when available, provided a measure of the external gamma doses to persons wearing, or represented by, film badges. The primary source of recorded film badge dose data is the file maintained by Reynolds Electrical & Engineering Company, which is the official master repository of dose records for nuclear weapons tests. Using contractor support, DNA is providing reconstructed doses that reflect the entire period of exposure, as well as exposure to neutron radiation or internal emitters, for those cases where the recorded dosimetry did not represent the full circumstances of exposure. These dose deter- minations, described in chapter 7, are based on specific unit activities and the actual radiological conditions. Doses so determined have correlated well with film badge readings when the circumstances of exposure are generally known. Findings to date indicate that most external gamma doses to personnel at the tests were quite low--averaging about a half a rem. Many participants received no dose at all, and less than one percent exceeded 5 rem, the annual whole body dose limit recommended by the National Council on Radiation Protection and Measurements. Table 4, given at the end of this section, presents data provided by the NTPR teams that show the breakdown of all external gamma doses, both recorded and reconstructed. The dose totals given in table 4 do not precisely match the estimated numbers of participants for the specific test series given in chapter 4, except for ARGUS, or the estimated total number of DOD participants in the atmospheric nuclear tests. In some cases, multiple badging of individuals led to more doses than participants; in other cases, participants had no film badge doses and reconstructed doses are pending. 19 Moreover, the film badge
