reassessment will be extended to apprupriate locations based on resuits of previous Pu bioassays. A whole-body counting unit will be’ constructed at Majuro along with computer facilities to handle the deta base. A radiochemistry lab will be constructed at Majuro for urine bioassays of gamma emitters. A Health Physicist and Radiochemist will continue to train. Costs for these transition items are indicated in Number 8 above. It is to be emphasized that these transition costs are in addition to 1985-1989 normal program costs (l-7 above). During FY 1987 a summary of dose reassessment will be completed for Likiep and other atolls of interest. A bioassay mission to Enewetak and the locations of former Bikinians will be performed. summarized. Radiological experience at Enewetak and Bikini will be Training will continue and the Majuro radiation protection facilities made Operational. During FY 1988, a bioassay mission to Rongelap, Utirik, and Enewetak will be performed. Long-term retention exhibited by former Bikinians will be factored into dose assessment models. Whole-body counting calibration and comparison between the MIG unit and Laboratory units will be performed. Transition costs account for this intercomparison and calibration. Training will be finalized. During 1989, a mission to Enewetak will occur. urine and computer updating will continue. Whole-body counting, bioasssay of Efforts to link medical and dose data will continue. Advantages for MIG to exercise buy-back options inciude no startup costs, no transition costs, no hiring of permanent employees and availability of state-of-the-art research facilities. Advantages for the U.S. to maintain these programs include collection of long-term health and radiological data regarding exposure to fallout and no expenditure for transition costs.
