Mr. Roger Ray July 18, 1985 Page 3 We have also considered thyroid nodules and current blood cel! counts as they may relate to early residence on Rongelap, since a greater radiation risk would have existed during the early years after the 1954 fallout. Thirty-four persons in the Comparison group resided in Rongelap for 4-6 years commencing with the return to the atoll in 1957. Only 1 nodule, an “occult carclnoma",, has occurred in this subgroup (3.0%), whereas the other 6 nodules, including the two true thyroid carcinomas, occurred in the other 99 persons in the Comparison group (8.1%). There was also no difference in blood ce]] counts: Time of Residence Early Late Humber Tested (1985) 29 77 Neutrophils/ul #SD 403281543 434921599 Lymphocytes/ul __ $50 Platelets/ulx10 27134636 27562951 #SD_ 261497 264280 If you wish us to examine any other parameters do not hesitate to ask.
