Analysis of Radiation Exposure for Observers and Maneuver Troops. Exercise Desert Rock IV, Operation Tumbler-Snapper.

: The radiation doses to observers and maneuver units for Exercise Desert Rock IV are reconstructed for each applicable shot of Operation Tumbler-Snapper (1952). Residual radiation doses are calculated by using an automated procedure to couple scenarios for troop activities to the radiation environment. Uncertainties are determined for each parameter. Possible exposure to initial radiation and internal doses are also assessed. The calculated film badge equivalent doses range from 11 mrem (paratroop units, Shot charlie) to 370 mrem (maneuver troops, Shot Dog). Initial doses were negligible for all participants at all shots.
