The Navy Department with the approval of the Joint Chiefs of Staff is undertaking a scientific re-survey of Bikini Atoll particularly with respect to Test Baker during the summer of 1947. The expedition expects to leave San Diego July 1 and begin operations at Bikini about July 15 to last approximately six weeks. Admiral Parsons, Chairman of the Joinl Crossroads Committee, has that the Commission should support the expedition by authorizing and underwriting a group from the University of Washington, Dr. Donaldson and about ten of his associates, at a cost of approximately $25,000. It was not deemed advisable at that time to agree to the inclusion in the expedition of Drs. Overstreet and Jacobson, of the University of California, nor sny other radio-chemists from California, Argonne, or Clinton since it was felt radio-chemical analyses could only be carried on adequately at home laboratories in the States. On 9 June, Li -o-) requested the Commission, via the Military Liaison Committee, to approve Admiral Parsons! request for the requirements of the Joint Crossroads Committee. Commander Revelle first approached General McCormack and stated the views contained in memorandum prepared by General McCormack. Commander Revelle was referred to the writer, and the memorandum of Admiral Parsons discussed was supported with names and requirements. On June 6, Mr. Wilson and the writer met with Dr. Stafford Warren to Giscuss the Bikini expedition. At that time, a conclusion was reached the writer explained the above position to Admiral Parsons who reiterated the need for Drs. Overstreet and Jacobson as essential to the expedition for the supervision of the collection of samples, determination of the locations to take samples, and evaluation of the sampling work done at Bikini. It was not felt necessary to have other radio-chemists join them. The writer reluctantly agreed that if Drs. Overstreet and Jacobson can agree to go, the Commission would probably approve. This opinion was checked with Mr. Strauss who indicated concurrence. However, Admiral Parsons has now telephoned again, apparently after talking with Commander Revelle, and has requested additional radio=chemists to accompany Drs. Overstreet and Jacobson, namely Mr. Larsen and a Lt. Col. Hirsch, of the University of California, the latter of whom is MAY assigned to Special Weapons, and two other technicians from Clinton Laboratory \e VEN who have apparently indicated they" would like to go on the expedition. —D§ j amnemel BEST COPYAVALLASLE
