IV. Surviving adult Utirik people exposed to fallout, dose: (Estimated 14 rads external gamma plus 15 rem internal irradiation.) Total - 120 1, One person developed a nodular thyroid gland and underwent surgery in 1969, As the tissue resembled a follicular adenoma in frozen section, a total thyroidectomy was performed; histologic sections confirmed the diagnosis and upgraded the degree of malignancy. She has recovered satisfactorily, 2. One person with slight enlargement of one lobe of the thyroid to be treated conservatively and observed. One case of nodular thyroid has been found in a non-exposed Rongelap woman living on Ebeye. Thyroid surgery has been recommended for this patient at Majuro Hospital. No other instances of thyroid abnormal- ities have been found in the control populations living on Utirik, Majuro or Ebeye, kk * It appears that the exposed populations have stabilized so far as the thyroid. reactions are concerned. Since the delayed reactions by the thyroid are a possibility, Dr, Conard proposes that this population continue to be kept under observation, por CHIVE= Dr, Conard notes that the Bikini people now living on Kili are putting increasing pressure on the Trust Territory for return to their Atoll before the restoration is complete and the land can support a population, This movement may cause the Trust Territory to ask that all radiologic and safety activities be accelerated so that decisions can be made as to construction of homes, cisterns, etc., ahead of schedule, A low key public announcement of the above observations is being considered by the Brookhaven public relations office. The same information is being forwarded to Mr. Bauser for the information of the Joint Committee on Atomic Energy. NMak) ASrcwey le 9 John R, hone Director Division of Biology and Medicine
