C OFFICIAL USE ONLY ee. RADIOLOGICAL REPOST ON BIKINI ATOLL Introduction Reports on this subject were prepared by Philip F. Gustafson in April and May 1963 (Attachments 1 and 2). Since that time the de- | cision has been made that the Bikini people may be returned to their Atoll but that certain measures should be taken to further reduce radiation exposures. These measures are described in the report of the AEC Ad Hoc Committee (Attachment 3). During 1969, cleanup of Bikini Atoll, which was one of the Ad Hoc Committee's recommendations, was accomplished through a cooperative project funded by DOD and AEC. The Atoll has now been turned back to , the Office of Trust Territories of the Pacific, Department of Interior. DOI is currently cenducting a prezgram of agricultural rehabilitation that has been under way aboutone year and construction of housing and community facilities is to begin in the near future. The cleanup project provided an opportunity to obtain significant additional information on the levels of environmental radiation and radioactivity in the Atoll. Enouch of the results from the 1969 monitoring and sample collecting activities are now available fron Allen Smith and William Moore of SWRHL and from Fdward Held of the University of Washington to make preliminary comperisons with the 1967 results and to determine what if any differences the 1969 data maay make in radiation extosure estimates prepered by Dr. Gustefson.
