Mr. Roger Ray July 18, 1985 Page 3 We have also considered thyroid nodules and current blood cell 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 ato]] in 1957. Only 1 nodule, an “occult carcinoma",, has occurred in this subgroup (3.0%), whereas the other 8 nodules, including the two true thyrold carcinomas, occurred in the other 99 persons in the Comparison group (8.1%). There was also no difference in blood cel! counts: Time of Residence Early Late Number Tested (1985) 29 77 Neutrophils/u] #SD 603221543 434921599 Lymphocytes/ul ___ #50 Platelets/ulx10 #SD_ 27132836 2674257 27562951 264280 If you wish us to examine any other parameters do not hesitate to ask.
