-5- of those presently measured in the Rongelap people the the same. 90 Sr levels were about Since the Bikini inhabitants have been subsisting largely on imported food these findings would seem to indicate that they are eating some plant foods grown locally, though their consumption is forbidden. The limited intake of domestic livestock would indicate that this is a minor source. Fortunately, pandanus and breadfruit, the two main plant sources of these isotopes are not available yet in any great quantity 4nd measures are being considered to transplant these plants to Enue (the nearby less contaminated island) in order to remove the temptation for eating them. The drinking water from the wells and catchments would not appear to offer a significant contribution to the body burdens since the radionuclides present are well below theMPC. Marine life at Bikini has been reported to contain very low levels of radionuclides and apparently offers no problem. The coconut crabs have high enough levels of these radionuclides to be banned from the diet of the Bikinians and are very scarce in any event. The present body burdens of people would not seem to be a cause for concern. 137CS It is is a relatively higher Sr-Cs ratio in the Bikini people Rongelap people. Attempts will be made to determine if and 90Sr in the Bikini
