Abstract : The radiation doses to observers, including volunteer observers, for Exercise Desert Rock V are reconstructed for each applicable shot of Operation Upshot-Knothole (1953). Initial neutron and gamma doses are determined from radiation transport codes. The several components of initial radiation are evaluated separately in order to consider the cloud dynamics and the effect of body positions on initial doses. Residual doses are determined through an automated procedure that utilizes raw data in regression analyses to fit space-time models. Observer activity data are combined with the refined radiological data to determine integrated dose. Uncertainties are calculated for each parameter. The relationship of internal dose to the radiological environment is also discussed. The highest calculated doses received by volunteer observers was 14 rem gamma and 28 rem neutron at Shot Simon. The highest gamma dose received by other observers was 1.3 rem at Shots Badger and Harry. Neutron doses for all other observers was less than .02 rem at any shot.
