THE CONTRIBUTION OF MEDICAL EXPOSURE TO THE RISK OF CANCER AMONG “MAYAK” PERSONNEL

Osipov M.V., Sokolnikov M.E.

Purpose. To assess the contribution of medical exposure to cancerigenic risk in a cohort of "Mayak" workers.
Southern Urals
Biophysics Institute.
Ozersk, Russia.


 

Materials and methods. The study was conducted in a cohort of workers hired from 1948 to 1972 with 60 years follow-up period. Data on an individual X-ray dose, as well as professional gamma-dose, were obtained from the "Dose-2008" dosimetric system.  Mortality data were obtained from the register of death causes of the “Mayak” workers.

Results. The structure of X-ray examinations in a cohort has been shown, the validation of choosing the reference dose for dose-response analysis has been provided and the excess relative risk (ERR) per unit dose of medical and industrial radiation have been calculated.

Conclusions. Received estimates of medical exposure contribution to carcinigenic risk can be used for the purpose to value the levels of medical exposure.

Keywords: cohort study, cancerigenic risk, medical exposure, dose of medical exposure, excess relative risk.
