Considerable difficulty in clearing personnel was encountered because such additions to the roster occurred, In approximately twelve cases, requests for Q clearance did not reach the FBI until about 12 January 1951, and as of 6 April 1951 (D-2 days) seven enlisted men of TU 3.1.5 remained uncleared. It was only by changes in JTF-3 orders on or about 20 March 1951 that uncleared personnel who had been certified by their commanding officers as good security risks were permitted to remain on Parry Island and continued use of their services could be planned by CTU 3.1.5. For future operationsit is desirable that five or six months be allowed for obtaining Q clearances. One person of TU 3.1.5 was cleared in exactly three months after the request for clearance reached the FBI, All others required considerably more time. It is immaterial whether the delay in granting clearances is due to time needed for the FBI investigation or to time needed for processing within the AEC. Movement of supplies and equipmentto the Forward Area continued. In general, the supply and equipment situation was excellent throughout Operation Greenhouse. The only major items of equipment with which difficulty was experienced were the AN/PDR-T1B Radiac training set and Mine Safety Appliance Co. dust collectors. Eighty-five of the Radiac training sets were ordered and scheduled for delivery in the Forward Area on 1 February 1951. A change in the original order specified that the instruments were to be equipped with batteries and that 100 per cent replacementfor batteries would also be furnished. On 31 March 1951, 60 of the AN/PDR-T1B’s were delivered without batteries. Batteries for 10 AN/PDR-T1B’s were obtained, and the instruments were used during Dog shot operations. The remainderof the instruments and sufficient batteries for all 85 AN/PDR-T1B’s arrived shortly after Dog shot and were available for the remainder of Greenhouse, The Mine Safety Appliance Co. dust collectors did not arrive until shortly before the last shot and were of little use. Movement of personnel to the Forward Area began on 14 February 1951 with the departure of the USNS General Aultman from San Francisco. The Auitman carried 27 officer monitors and TU 3.1.5 staff and reached Eniwetok on 27 February 1951, Gen Cooney arrived by air on the same date and on-the-site organization, training, and operation of TU 3.1.5 began. The next major movement of personnel, including mostof the enlisted men, arrived on the USS Curtiss on 8 March 1951. Small groups and individual members of TU 3.1.5 continued to arrive until about 28 March 1951, when the roster of TU 3.1.5 could be considered essentially complete. The staff of TU 3.1.5 was organized as follows: Commander Brig Gen James P. Cooney, MC, USA Lt Col James B. Chubbuck, CE Dr. Thomas N. White, LASL Dr. Howard L.
