In printed version these were 169 and 403, respectively.
We used
the risk coefficients that were derived for continuous exposure.

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.
