Dr. Robert A. Conard, Medical Department, Brookhaven National Laboratory, who has responsibility for conducting the clinical surveys, reports: "Sections of the nodules have been examined by a number of pathologists including Drs. S. Warren, G. H. Klink, H. A. Johnson and S. Lindsay. The concensus is that the nodules are benign, though with certain bizarre areas, and resemble iodine deficiency adenomata.” ‘ Dr. Lindsay noted that the nodules in the Rongelap cases are similar to ones he has seen in children following 113 therapy. This Division has a file of Dr. Lindsay's histological reports and a review paper by Lindsay and Chaikoff, Cancer Research, 24:1099, 1964. The radiation dosages which these children's thyroids may have received are being re-evaluated by Dr. John Gofman'’s group, Lawrence Radiation Laboratory. It should be added that nodules in the thyroid glands of young people frequently become malignant in the course of time. Therefore, while these which were removed promptly after discovery were not malignant, there is a chance that in time they might have assumed neoplastic characteristics. Dr. Conard's next clinical survey will tzke place in February 1965. BEST COPY AVAILABLE €. L. Dunham, M.D. Director Division of Blolozy and Medicine Attachment: Copy of mero dated 10/2/64 from C. L.
