Dose-Response Relationships host factors

The accumulation of human data on a wider scale, and in quantitative form, has enabled radiation epidemiology to advance from an essentially descriptive stage to an analytic one in which numerical, dose-spedfic, risk estimates have begun to be treated statistically in order to identify determinants of risk. As presently conceived, these determinants include characteristics of the radiation exposure, underlying dose-response relationships, host factors, other environmental factors, differential tissue sensitivity, time after exposure, and natural levels of incidence.
