The final shot of the Castle certes, ME was fired from the control room on Parry Island, This was thé series made at Eniwetok Atoll. 6nly detonation of the j During Operation Castle no misfires or other delays were encountered which were due to the arming or firing operations, Weather difficulties did interfere with the firing schedule, however, and these delays necessitated arming and disarming all but two of the devices more than once. TASK UNIT 7, RADIOLOGICAL SAFETY 4.6.1 Introduction TU-7, the radiological-safety unit for TG 7.1, was a continuation of the radiological-safety unit of TG 132.1. Preliminary to the Castle operational phases, personnel to staff the unit were requested from the voyte 4.6 Arny, Navy and Air Force. The Army furnished 34 persons, and the Navy 11. Civilian technical advisors of Health Division, LASL, and the U.S. Public Health Service were added to ~he unit just prior to and during the overseas period, 4.6.2 Task Group Organization for Radiation Safety Early concepts for Castle indicated & high requirement for radiation-safety monitors. In past operations these monitors were furnished from personnel of the radiological safety task unit. The continuation of this policy would have meant a large unwieldy organiza- tion and an expensive service. An alternative was proposed and accepted by the Task Group Commander. This alternative was to place radia- tion-safety responsibility with the commanders and project leaders and to require each: project to provide its own trained monitorea, Training of Rai-Safe monitors was to be accomplished by Fed-Safe task unit per- sonnel, A reserve monitor pool was also to be established by TG 7.2 in case of emergency need, The monitor, from the unit concept, would act as radiation-sefety advisor to the project leader. Establishment of this policy enabled TU-7 to reduce its operational personnel to a small skeleton staff of 43 personnel supplemented by project monitors of LASL, UCRL, and DOD. The skeletal organization was divided between Eniwetok and Bikini along the following lines: CocledsDOE LANL, J-Diy. 109 . . “ q
