Atomic bomb survivor waiting times. The EAR parameters F_k of Equation (1), fitted separately to male and female atomic bomb survivor data, are shown. The results indicate that radiation-induced CML incidence decreases with time. Male latencies are < 20 years and female latencies are bimodal with one mode at ∼ 5 years (similar to males) and the other at ∼ 32 years. The Wald 95% confidence interval of the female F_k parameter shown at ∼ 32 years does not include the corresponding male point.
