Safety Studies and Development of Operational Guidelines Marshall Islands Radiological Safety Program RW-03-(a) Project Title: 16. Technical Progress in FY 1976 and Transition Period: (Cent’d.) June-July 1975 in which BNZ participated. Data from both these surveys are currently being used to refine dose and dose commitment predictions for returning Bikini residents. BNL collaborated with the University of Washington LR_E in a regional radiological background study in Micronesia, November-December 1975. Data from this study will be used as a reference base against which radiological data from the northern Marshall Islands can be compared. The first routine followup study for Bikini .sndEneu is scheduled for April 1976. This survey will include detailed radiological profiles of the Nam-Bokata complex of islands which are the next areas scheduled for agricultural development in the Bikini atoll master plan. 17. Expected Results in FY 1977: Ground survey support will be provided for a planned interagency aerial radiological survey of all previously unsurveyed atolls in the northern Marshall Islands which may have received local fallout from the U.S. atmospheric nuclear tests. Enewetak will be visited by the program principals in order to establish a routine environmental monitoring program for that atoll. Continued technical support will be provided by BNZ for the ERDA-funded Pacific Basin radiological program of the University of Washington LRE. 18. Expected Results in FY 1978: Continuation of programs described in FY 1977. 19. Description and Explanation of Major Materials, Eauipment and Subcontract - Items: Caoital Eauipment Fiscal Year 1977: Additional memory and an x-y plotter ($9,000) for the Ge(Li) spectrometer system is needed to improve sample analyses and data processing capabilities on large numbers of environmental samples collected during field surveys. Peripheral electronics (S6,000) for a thin intrinsic germanium detector array is needed to process soil samples for heavy elements. Capital Euuipment Fiscal Year 1978: In FY 197S a standard compatible magnetic tape unit ($7,900) will be needed for data storage, which will enable the scientific staff to transfer (See Continuation Sheet) RW-5
