[64]; Moolgavkar and Knudson [65]). In radiation epidemiology the first deployment of BBCR models occurred with the Life Span Study (LSS) of Japanese a-bomb survivors decades after their application to observational cancer data (Little et al. [55]; Little [54]; Heidenreich et al. [37]; Kai et al. [42]). Early pioneering studies of radiation risk in the LSS were based on descriptive models which linked excess rates of cancer incidence and mortality to radiation exposure by statistical association (Wakabayashi et al. [85]; Thompson et al. [82]). Persistent radiation effects and radiation-associated inflammation Radiation can modulate cancer initiation, progression, and transformation in multiple ways thereby leading to multiple cancer types.
