There was no camp on Bikini Island and any work done there was performed by workers brought by boat each day from Eneu Island. The work crew of more than-213Bikinians who are participating in the agricultural rehabilitation project rotates every three months from Kili Island, the present home of the Bikini people. Because of the limited facilities on Eneu Island, workers were not allowed to bring their families to Bikini Atoll even for a three-month period. Unless this restriction is removed, the first families may not return until 1972 or later. Those working in the Atoll are experiencing problems with cmununications, water transportation and equipment maintenance. Laboratory analysis of air filter samples collected over a twoweek period on Eneu and Bikini has been completed. Table 1 presents data for five stations on Bikini and four on Eneu. The values listed were obtained by analyzing one half of the filter for each day canposited by station over the total sampling period. The remaining half of these daily air filter samples is on file for possible future use. For comparison the Maximum Permissible Concentrations, MPCts, are included in the Table. Details of the location of the air samplers will be presented in a later report. The only unique aspect of sampler location is for Station 1 on Bikini wherein this sampler was exposed to dust from the jeep driven by the survey team members along the lagoon road. Table 2 presents the average valu’efor Plutonium-239 in air at Station 1 on Bikini for each of foqrteen consecutive days. The average value in the U.S. in 1968 is shown for comparison. It was expected that results for ahalysis of soil samples would be available in late September or early October. It now appears these results will not be available until the latter part of November at which time a more complete report of the 1970 Bikini survey can be prepared. Included will be data on air, water, soil, aq;regate, algae, rats, goat fish, lobster, coconut crab, exposure rates inside and outside bunkers and inside and outside a cistern built with local sand and aggregate in 1969, the shielding =periment, Bravo crater muck, and on urine ssmples for one Trust Territory resident and one team member. -4’-
