DOB ARCHIVES The major medical problem is to persuade the people to take their thyroid hormone supplement on a regular routine schedule, This has not yet been solved, To summarize, all but 2 of 19 children exposed on Rongelap have now exhibited thyroid dysfunction as have a smaller but significant number of adults. Statisrics on the frequency of thyroid cancer in Micronesians do not seem to be available; the figures for 25 countries around the world range from 0,25 (Japanese males) to 1.54 (Austrian females} per 100,000 population. Dr. Conard also visited Bikini to collect urine samples from the 25 Bikini men temporarily there working to rehabilitate the island; these specimens plus coconut crabs will be analyzed for Sr, Cs and 238-23 Pu. Plans are going forward for whole body counting of the population before they return from Kili to Bikini. A low key public announcement of these findings is being considered by Brookhaven National Laboratory.
