SHIPBOARD RADIATION FROM UNDERWATER BURSTS.
Abstract
The project had only limited success in meeting its objectives for Shot Wahoo, but met most of its objectives for Shot Umbrella. The conclusions are meant to apply only to the specific test conditions and radiological environments encountered aboard the moored and washed target ships. The gamma radiation data indicated rapid rates of change with time after burst, and dependence upon distance from surface zero. These characteristics are summarized for the washed weather-deck areas. After Shot Wahoo, the weather-deck doses accumulated more slowly but eventually reached values on the order of 300 r higher than for Shot Umbrella, even though the ships were from 1,000 to 2, 000 feet farther from surface zero. For the washed weather-deck areas, the observed total radiation can adequately represent the remote-source radiation during the first 10 minutes after the shots. At least 95 and 98% of the total dose on the washed decks was attributed to radiation from airborne radioactivity for Shots Umbrella and Wahoo, respectively. (Author)
