In the most recent survey, 2 more cases of thyroid nodules in children who were exposed to fallout on Rongelap when they were less i | than ten years of age were found, This brings the total number of cases of thyroid abnormalities in the 67 living Rongelapese to 21; of the 19 children in the more heavily exposed group who were less than 10 years of age at time of exposure, 17, or 90% have developed thyroid abnormalities. It was decided that 4 cases should be brought to the Brookhaven National Laboratory for complete medical evaluation and, if necessary, surgery. Preparations for their transportacion and reception are now taking place. Three are people having thyroid nodules which had not responded to thyroid hormone therapy. The fourth is a 29-year-old woman with an unidentified tumor in the neck lateral to the gland. In the past, 1l Marshallese have undergone surgery; one woman exposed as an adult wes founda to have cancer of the thyroid, while 10 who were exposed when less than 10 years of age had benign adenomatous goiters,
