Risk of diseases induced by internal radiation

Risks of diseases induced by internal radiation for different scenarios of annual exposure to radiation were assessed. In the scenario it is assumed that absorbed doses to organs and tissues are formed mainly due to inhalation of radionuclides. Results of study demonstrate that if internal radiation is due to inhaled radionuclides, organ dose is located in respiratory organs primarily, operational state of NPP is normal, lifetime attributable risk for nuclear workers can be assessed. Effective dose can be considered as approximate estimate of possible harm to health of those exposed to radiation at the age younger than 25 years.
