47 DELETED a nN Ce Task Group 7.4's mission, as already stated, was to perform nuclear cloud sampling, aircraft effects measurement and technical photography as primary functions, and inter~island and intra-atoll airlift, weather reconnaissance and reporting, air rescue and communications as secondary functions. A. NUCLEAR CLOUD SAMPLING The sampling program consisted of collecting particulate and gas- eous matter from the atomic cloud. Particulate samples were collected on a special type filter paper in specially designed wing tip tank filters. Gaseous samples were pumped by special devices into bags or bot- tles in the aircraft. " The Los Alamos Scientific Laboratory and the University of Califor~ nia Radiation Laboratory indicated the quantity of samples desired and allowed Task Group 7.4 to establish the aircraft requirements necessary to take this quantity. Two B-36's, fifteen F-84G's and one WB-29 were designated as samplers, ; Nuclear cloud sampling was the task of locatingand obtaining, for radiochemical analysis, the best possible representative samples of radioactive particles available throughout the nuclear cloud which ensued os SY
