Morimoto Division Leader Fnvironnental Sciences Lawrence }|.ivermore Laboratory Livermore, California 94550 Dear Ed: During your December visit we agreed to detail what is needed in the next round of dose estimates for Bikini. As you know, it is our commitment to conduct a program of radiological follovw- up ane to periodicaily reassess radiological conditions at Bikini. LLL dose estimates along with the Brookhaven, PIL, whole body measurements are the end products of this followup. These measurements and predictions are key elicments in developing advice for Department of the Interior, DOI, and Department of Desfense, DOD. With the recent evacuation of Bikini Island last August, the next question is whether or not Eneu Island can be used es a village island end still maintain exposures of residents within the acceptable standards. Past data has not provided any cptimism on the answer to this question. DOT is anxiously ewaiting the new information. We are committed to providing this information and subsequent advice to DOI by the end of January 1977S. We nave listed and enclosed suggested options relative to the assessment of FEneu as a village island. Any suggestions you have would ke most welcome. We would of course be pleased to discuss this with you and Bill Robison. Sincerely, \ ¢ a [ | de y L.-Joe Deal, Assistant Director Division of Operational and Environmental Safety ce: R. J.
