was for four very-high-yield detonations. ule was enlarged to seven shots As plans progressed, the sched- (reduced during the operation to six). Since each extra event was potentially dose-additive to many of the participants, the permissible exposure per event decreased as the number of shots increased. Radsafe planning was designed, in part, to minimize the number of people who might be exposed above the general criteria level (Reference 16, p. 17). This required either exposure of a greater number of people, or provisions for exposure waivers for some personnel. The Joint Task Force Radiological Safety Plan was cognizant of these points. 3-53 Published as Annex N to Reference 9, Task Force Operation Plan (see Appendix A), the plan established radiation safety as a command responsibility, as did Annex I to Reference 19, Operation Order 1-53 Appendix A). (see The plan also specified safety criteria for the entire task force and defined specific task group responsibilities and missions for applying these criteria. Information developed during preceding test se- ries, particularly Operation Ivy, formed the basis for the plan. The radsafe plan for each task group was derived from the Joint Task Force Plan. It laid out in detail the application of safety criteria in the context of operations for each service and outlined procedures for implementing them, including training, installation of equipment aboard task group ships, monitoring, and decontamination of personnel and equipment. Organization and-Responsibilities Overall organizational planning and authority for radiological safety rested with the CJTF 7. The Commander's staff coordinated radsafe infor- mation collected before and during shot operations and also maintained liaison with the Commander-in-Chief of the Pacific radiological exposures outside the PPG. (CINCPAC) regarding Elements of control existed at all command levels, and operational control was applied through normal command channels. A decentralized system of operational control, utilizing elements of the CUJTF 7 staff and units within each task group, was established for 76
