I would in fact prefer that such information be: provided to DOI through EV unless otherwise directed. Please inform me as to your preference. In the meantime, the following information is the best we have to date in response to the questions which you raised: 1. We do not know (and have no means immediately available to estimate) how many people may have lived at Bikini Atoll between 1969 and 1978. When we began field trip visits in 1974, there were approximately 40 people {presumably Trust Territory-employed caretakers and their families) Living on Bikini Island. The population grew over subsequent years until August 1978, when all -140 persons then in residence were moved to Kili. We-are uncertain about the breakdown, but some of the 140 had land rights on Bikini, while others were T.T. employee families without land rights. 2. In April 1978, the BNL medical team conducted sick call at Bikini Island. At that time, a census was conducted and 135 persons were living on Bikini Island. Some individuals were not present. We estimate that the island population was between 135-145 with 140 as the most probable figure for April 1978. Of the 140 persons, 30 persons were estimated to be less than 5% years old, and 22 persons less than 2 years of age. We have assumed that the number of persons relocated in August 1978 was essentially the population of April 1978. 3. Bob Miltenberger had an opportunity to discuss population statistics on May 19, 1979 with Tomaki Juda (a member of the Kili Council) and Ralph Waltz (a Kili Council spokesman). They stated that during the entire post-testing period during which Bikini was inhabited (-1969 to 1978) only 2 or 3 (extended) families having land rights at Bikini ever lived Lhere. These families comprised about 15% of the total population, the remaining 85% being T.T. employees and their dependents. The following table presents our best information to date in response to your questions 7%, 4, 5, 6 and 7. BEST COPY AVAILABLE
