DRAFT 25 19 Oct 64 MEDICAL Of the three girls diagnosed with thyroid tumors in March 1964 two have had thyroidectomies and have been diagnosed with adenocarcinoma. Thethird is soon to have a thyroidectomy. Estimated doses to the thyroids are "100 to 175 rads external gamma plus 100 to 150 rads from absorbed radioiodine." Pending documented data, however, the AEC considers these findings “tentative.” While the two girls’ prognoses are uncertain, the surgeonsfeel "they may have removed all the neoplastic tissue."'” Mar 65 CONTRACTOR MEDICAL . Conard’s survey reveals that while the “health of both the exposed and unexposed people... is generally good, and ... nutrition ... satisfactory," three more cases of thyroid nodules are discovered: two boys and a 41-year-old woman. These people are being brought to BNL for “further examination and treatment." To date, no malignancies that can be "related to radiation” and no cases of leukemia have surfaced. In addition, the people’s "blood elements" have returned to normal; they “appear well adjusted to life on their home island and exhibit no untoward psychological reactions to their experience.""@ | May 65 CONTRACTOR RADIATION A study of gamma dose rates at Rongelap Atoll, done by the LRB between 1954 and 1963,reveals that the decline of these rates from 1954-1959 "followed the theoretical decay of mixed fission products from U** calculated by Miller and Loeb." From 1959-1963, the reduction was “approximately half the predicted levels," but this is attributed to the "downward movementof the long-lived gamma-emitter Cs” in the soil.” July 65 © M ADMINISTRATION... | CONTRACTOR *. MEDICAL All three thyroid cases found during the March 1965 survey are successfully operated on at the Lahey Clinic in Boston. The tumors in the two boys are found to be benign. The woman, however, "has carcinoma of the thyroid gland with some metastases to local structures." Sheis given a "sub-total thyroidectomy” followed by 30 millicuries of iodine’. Of note is that the radioiodine dose in the womanis approximately 160 rads, or one-tenth that of the youths.
