General term indicating estimates of lifetime risk due to a given radiation exposure. Several types of lifetime risk estimates can be used to calculate the risk, over a lifetime, that an individual will develop, or die from, a specific disease caused by an exposure: 1) the excess lifetime risk (ELR) which is the difference between the proportion of people who develop or die from the disease in an exposed population and the corresponding proportion in a similar population without the exposure; 2) the risk of exposure-induced death (REID) which is defined as the difference in a cause-specific death rate for exposed and unexposed populations of a given sex and a given age at exposure, as an additional cause of death introduced into a population; 3) loss of life expectancy (LLE) which describes the decrease in life expectancy due to the exposure of interest; and 4) lifetime attributable risk (LAR) which is an approximation of the REID and describes excess deaths (or disease cases) over a follow-up period with population background rates determined by the experience of unexposed individuals.

The LAR was used in this report to estimate lifetime risks.
