B. BEIR-III 1. Cancer (Table V-4 of Typescript Edition) Lifetime Risk of Cancer Death (deaths/10°/rad) Single exposure to Continous 10 rad xposure to 1 rad/yr Model Absolute Relative Absolute Relative L-Q, LQ-L 77 226 67 182* L-L, L-L 167 50] 158 430* Q-L, Q-L 10 28 --- --- * In printed version these were 169 and 403, respectively. We used the risk coefficients that were derived for continuous exposure. 2. Birth Defects--pages 166-169 (mean parental age = 30 years) 1 rem per generation (1 rem parental exposure) per 10° live off- spring 5 to 75 birth defects, this is 0.0005--0.0075%--First generation. Since the spontaneous rate is given as 10.7%, in the U.S. population, 1 rem will increase the rate from 10.7% to 10.7005--10.7075%. In terms of the spontaneous rate 1 rem per generation gives oe 0.000047 = 0.0047% increase and OOF = 0.0007 = 0.07% increase. IV. CALCULATIONS OF RISK Table 1 gives the radiation dose values provided by Dr. Robison for use in developing estimates of increased health risks in the Bikini population. A. Risks for 14 Different Living Conditions 1. Cancer Risks Table 3 shows the calculations for estimates of increased cancer risk for 14 different living conditions.
