The time-delay, between the radiation exposures and the diagnosis of clinical cancer, is called the incubation period or the latency period.. We know for certain, from the study of the Atomic-Bomb Survivors in Japan, that the latency period varies enormously among individuals.he time-delay, between the radiation exposures and the diagnosis of clinical cancer, is called the incubation period or the latency period..
