Therefore, one should be For example, the long-lived radio- nuclides of Ni®3 and ag 8 were not suspect for the first two decades of study at the Pacific Proving Ground. However, when it became obvious that these species would have to be formed in the blast it became routine to find these in all parts of the food chains. On this basis, we would not rule out the existence of 129 Tc?? and a great variety of transuranics showing up in various parts of the food chain. The meager 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 dietary habits developed by the natives after moving to Ujelang using imported rice, flour and sugar - will help reduce the daily ingestion of radionuclies. Add information on current diet of the people on Ujelang, indicating amount from local, natural sources (sea and crops) and amount of imported food consumed. Give any available informa- tion on diet of infants and children which may be appropriate.
