-3overt genetic and somatic damage will occur to the -eehatrttitetedNatives due to either external or internal doses, no previous information is available relative to the special concentration processes of the transuranics in tropical marine ecosystems-whether it be chemical, physical or biological. should be alerted to the unexpected. Therefore, one For example, the long lived radionaclides of Ni®? and Ag t08 were not suspect for the first two decades of study at the Pacific Proving Ground. However, when it became abvious that these species would have to be formed in the blast it became routine to find these in all parts of the food chains. Te 99 On this basis, I would not rule out the existence of 129 . . : and a great variety of transuranics showing up in various parts pf the food chain. The menmger human diet, naturally available, will consist of sea foods found in the reef, tidepools, lagoon and open sea; fruits and vegetables which can be harvested; and sea birds and their eggs. Cleanup and rehab operations should be designed to provide a minimum of impact on these foods. Continuation of the feeding habits developed by the natives after moving to Ujelang - using imported tice, flour and sugar - will reduce the daily ingestion of radio- nuclides. 7 - Flora and Fauna The effects of radioactivity existing in any part of the atoll on individuals and populations of plants and animals are likely to be very small. If they are detectable at all it will be only through qd,
