Abstract

The authors compare values of radiation risks of potential cancer from diagnostic radiation exposure assessed with the use of organ and effective doses. Estimates of lifetime attributable risk from CT scanning made with ICRP 103 risk models and national data of medical statistics are given as an example. It is shown that values of lifetime attributable risk based on organ and effective doses can differ 3.11 times. Values of lifetime attributable cancer risk for specific organs are presented as well.

Key words
Radiation risks, computed tomography, organ and effective doses, lifetime attributable risk.
