In July 1957, after careful evaluation of radioactive contamination, Rongelap Island was considered safe for habitation. A new village was constructed, and the Rongelap people were moved there by Navyship. (See frontispiece.) The annualsurveys are carried out at Rongelap and also at Kwajalein and Majuro Atolls, where a number of Rongelap and Utirik people now reside. Examinations on Utirik Atoll are carried out about once every 3 years. A group of more than 100 Rongelap people, whowererelatives of the exposed people but had been away from theisland at the time of the ac- = cident, moved back with the exposed people to their home island and have served as an ideal comparison population for the studies. The number has since increased to >200. Since the accumulation of data from these surveys is becoming increasingly voluminous, survey reports published by this Laboratory are made as complcte as possible and include a considerabie amount of raw data, much of it in appendices, so that others may have access to complete data. A summary of early andlate findings covering the entire 15-year period is presented at the end of this report.
