No new cases of nodular thyroids were found during a visit to Utirik, nor were nodular thyroids found in controls on Likiep and Kwajalein Atolls, 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. Statistics 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.a coconut crabs will be analyzed for Or, 37¢s and Plans are going forward for whole body notin 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. The same information is being forwarded to Mr. Bauser for the information of the Joint Committee on Atomic Energy. John R,.
