Mr, Graves said the second experiment tiould involve the use of approximately six B-50 type airplanes which would be made available by APOAT-~1, These planes would be used to mal extensive measurements of local fallout over an expanded areé fore as long as ten hours following each shot. The third experiment would involve the use of airplanes which could flj at very high altitudes, measuring the amount of radioactive material in the stratosphere after each shot, Mr, Graves said consideration is being given to a four' experiment in which instrument-bearing rockets would be used to obtain data on the radioactive material in the mushroom cloud of one of the high-altitude shots. ment, In the fifth exper! two drone ships which had served the same purpose in Operation REDWING would be used to sample radioactivity prese in the ocean waters to a depth of sighty meters in the immedi areas of the shots, General Starvcird commented that these 3s! would cost approximately $1 million to $2 million. In respor to a question by Mr. Strauss, Dr, Shelton said thet these sh: nad been equipped for use in Operation REDWING and that it i: not practical to consider equipping smaller ships. General Stavbird cummented on the addittonal informatih vequested by the Departr-nt of Defense on fallout in the inte mediate areas and said thet the use of radioactive tracers, B-50 airplanes, and other high~altitude airplanes would prov: this information, He added vhat the cost of these experimen’ would be approximately $6 million, sut that neither the AEC : the DOD are sure of availabie funcs at this time, Genaral Starblrd said consideration is also being given to other expe ments involving rockets and ships to collect fallout data, } pointed out that the question of funds for the use of rocket: a2 -32-
