CHAPTER VII, SECTIONS 1 and 2 “Jue to the extent of the ultimate contamination, . heavy work load was imposed on the Rad-Safe (:roup and there were times when the evaluation of the film badges was not completed until several days after exposure. As a result, men were detailed to work in contaminated areas without current knowledge of their cumulative exposure. Because of this fact, several of the Contractor’s personnel received cumulative do- sages in excess of the 3900 mr per 13-week period. None of these overexposures were ex- cessive to the point of impairment of health. Nevertheless, it was the cause of considerable concern because of the always-present problem that these employees might claim damages based on such overexposure. The tests were completed. The successful integration of the Proving Ground’s Using Agency requirements with the mechanics of personne! assignment, transportation, radiological safety and evacuation was assured through mutual application and the cooperative spirit of the various components of the Task Force. SECTION 2 ROLL-UP The concept of the Pacific atolis of Eniwetok and Bikini as a permanent proving ground implies a reasonable re-use of its facilities and equipment. However, the nature of the Proving Ground’s function requires prolonged interrupt- ion of continuity in point of time. The term “roll-up” is applied to the salvaging of all supplies, facilities and equipment at the close of a test operation and putting same in such a state of repair and preservation that only minimum maintenance work will be necessary until re-use is required. At the close of one test operation, Fox camp buildings were dismantled and dif- ferent types of stored materials transferred; one walk-in reefer was left for food storage, and if the demand warranted, was to be supplemented by the site Tare mess facilities. The removal of equipment or materials from sites Nan and Tare was not considered necessary. For the orderly accomplishment of the fore- going, a schedule of events was formulated and another operation can be reasonably expected; yet due to the time element, a complete de- published. This schedule detailed, for each of the days of B minus five through B minus one, the actual facilities, equipment or stores to be removed on each day from Charlie and Fox to The Roll-Up Services detailed in Job V of Contract AT (29-2)-20 obligated Holmes & Nar- Elmer. The issue by TG 7.1 of a schedule for removal of scientific vans and other vehicles was of material assistance in coordinating the Con- mobilization must be met.

Materials and equipment not required, including User’s gear, are returned to the Z. I. , The roll-up commenced when the heavy construction period neared its end. After the equipment had served its purpose, it was returned to the Elmer base at Eniwetok Atoll where it was overhauled, sandblasted and painted (as required), and preservative was applied to moving parts before it was placed in storage. Prior to the initial test, the roll-up phase of the Operation began at Bikini Atoll. Con- struction equipment, installations, and stocks of warehouse material, in addition to scientific trailers and various types of User equipment, were completely removed from sites Able and Charlie. Only the essentials to maintain a 75man camp were left at site Fox. Many of the Page 7-4 Reoccupation of Nan, Tare and the reduced from Tare prior to the scheduled Koon event. Consequently, a mole was constructed at Nan for the beaching of LSTs in order to facilitate the final evacuation of Nan. However, due to the widespread destruction and radioactive contamination at practically all sites at Bikini Atoll following the Bravo event, plans for reoccupation were abandoned and all personnel thereafter were quartered on ships. Immediately following the Bravo event, notification was received that preparations for the future scheduled Bikini tests would be conducted from aboard ship. In compliance with the new instructions, only those Contractor personnel engaged in recovery and salvage operations were quartered aboard ship for speci- fic work assignments and were under Rad-Safe control.
