| In addition, there are new methods proposed for processing copra which have different operating conditions and produce different by-products. The products from these new methods need to be evaluated because it maybe possible that the radionuclide distribution wil be different, prehaps with the results that the products using these methods, may be more acceptable on the world ‘market. The importance of copra on the economy of the Marshall Islands, and on the “ economy of Enewetak and Bikini Atolls in particular, is of such importance that the experiments to determine the radionuclide distribution in copra products from the different methods should be carried out. Only limited studies have been possible in current programs. 5.) Transuranics in Fish The global experience in marine studies of the transuranics is too brief to model or to predict confidently concentrations of plutonium and other transuranics accumulated from the environment by marine organisms. It was recently found that the average concentration for 23942405 | in muscle of mullet from Rongelap Atoll] was Jarger than the average concentrations in these fish from other atolls, including the more contaminated atolls of Bikini and Enewetak. This unanticipated finding can be resolved through additional research at Rongelap Atol] in order to describe the environmental links transferring transuranic radioactivity to man. Of the transuranics, plutonium and americium to date have received the greatest attention in the radiological program at the Marshall Islands. Recently, however, curium has been detected in fish tissues from Enewet ak and Bikini and may be, by analogy, present in higher concentrations in fish from Rongelap. The internal dose to man from curium by ingestion of marine foods 39
