Two numbers must be clarified before a specific program can be established. The first is the number of groups. The Bikinian leaders have indicated that approximately 700 of the 925 Bikinians would probably want to resettle on Eneu. Using this number as an estimate, the 700 people could be : divided into two groups of 350 each or three groups of approxi- mately 235 each. of groups) The size of the groups (and hence the number should depend on the support facilities which can be constructed on Eneuand theotherislands west of the Eneu Channel. The second number which must be clarified is the length of stay at Bikini Atoll. One year seems to be a rea- sonable period for rotation, but there must be further discussion with the people of Bikini, as well as Department of Interior officials, before any final decisions are made with respect to either number. In the meantime, DOE should prepare annual and 30-year whole body and bone marrow calculated doses and risk assessments (based on population figures shown below, not a population of 10,000) 1. assuming the following living patterns: 350 people live 100% of the time on Eneu Island for one of two years (other year spent elsewhere in Marshalls). 2. ve. 350 people live 100% of the time on Eneu for one of three years.
