401448 Preliminary Report on Radionuclide Levels in Samples from Eneu Island and the Eneu Test Plot, Bikini Atoll May 1, 1978 The abstracted programs and preliminary results described below were initiated and are continuing with support from the Division of Biomedical and Environmental Research, Department of Energy. The Eneu test plot was established in August-September of 1977. The subsistence crops planted at this time were: Pandanus, breadfruit, papaya, banana, sweet potato, squash and watermelon. In addition to these subsistence crops, coconuts are now plentiful on the trees planted on Eneu in 1972. In August and November of 1977, coconuts were collected for analysis from a number of trees along with associated soi] samples. The preliminary results for !37Cs concentrations in these samples are attached. Data for 90Sp, 239+240py and 241Am concentrations will not be available before mid-summer 1978. In November of 1977, the squash and watermelon planted during August in the test garden were available for sampling. The collections have been processed and are presently being analyzed for specific radionuclides. 137Cs concentration data should be available for these samples this summer and the 29Sr, 2394240Am concentration data will hopefully be available this fall. | The breadfruit and Pandanus fruit were planted as root stock and will not produce- fruit for several years. | EL When the test garden was started in for fsk = J ,% aS ew 4 (972- fog (1715 WA 30 huh
