ITAEA-SM-224/607 115 other radiation syndromessuch as radiodermatitis, epilation, decrease of leucocytes, decrease of spermatozoa, etc. in the exposed Marshallese? R.A. CONARD: The thyroid doses in the Marshallese were based primarily on radio-iodine measurements in urine 15 days after exposure. Uncertainties included length of time of the fall-out, relative absorption from inhalation versus ingestion, etc. Therefore the doses are subject to error. The gamma doses received should be more accurate, as they are in agreement with the values estimated from the degree of haematological changes observed. The skin lesions, epilation and haematological effects in the Marshallese were similar to those reported by your group for the Japanese fishermen and have been described elsewhere. We were not able to do sperm counts on the Marshallese. No doubt there must have been some degree ofrelative sterility soon after exposure, though in subsequent yearsfertility does not appear to have been impaired.
