Improvement of the projection models for radiogenic cancer risk

Calculations of radiogenic cancer risk are based on the risk projection models for specific cancer sites. Improvement has been made for the parameters used in the previous models including introduc-tions of mortality and morbidity risk coefficients, and age-/gender-specific risk coefficients. These coeffi-cients have been applied to calculate the radiogenic cancer risks for specific organs and radionuclides under different exposure scenarios.
