Abstract

Internationally, the upper limit of acceptable individual risk from occupational exposure for nuclear industry workers is determined by the death probability 10-3 year-1. The same risk value of 10-3 year-1 is established by the Radiation Safety Standards currently in force in Russia. The United Nations Scientific Committee on the Effects of Atomic Radiation has proposed the formulae for estimating individual risk of developing cancer with allowance for radiation dose, age at exposure, attained age and sex. This methodology is first applied to estimate individual radiation risk for nuclear industry workers (49900 persons) who were monitored for radiation exposure through the use of personal dosimeters. The estimates show that in 2006 the threshold of 10-3 year-1 for individual risk is exceeded for 755 persons, which is 1.6 % of all workers covered by personal dose monitoring. The excess absolute risk (EAR) and attributive risk (AR) were estimated for all cancers, solid cancers and leukemias. The principles for forming potential risk groups are discussed.

Key words
Individual radiation risk, "dose matrix", nuclear industry workers, chronic occupational exposure.
