Forming groups of potential cancer risk from occupational exposure to radiation with the use of molecular and radiation epidemiological approaches

In the study forming groups of potential cancer risk from occupational exposure to radiation with molecular and radiation epidemiological approaches is discussed. Frequency of gene mutations at TCR locus was measured in 320 professionals of the State Scientific Center of the Russian Federation Institute for Physics and Power Engineering named after A.I.Leypunsky. Average accumulated dose get by the workers was 100 mSv. Due to the use of radiation epidemiological approaches to defining the workers with the value of attributable radiation risk of 10 % and more it was managed to increase the portion of people with increased level of gene mutations in the group. It is noted that the obtained results are preliminary because of limited statistical power of studies.
