[Micronuclear test evaluating cytogenetic effects of occupational radiation in low doses]

The authors compared cytogenetic injuries level among "Radon" staffers subjected and not subjected to occupational radiation. Both groups compared demonstrated no reliable differences in spontaneous frequency of micronuclear cells. Micronuclear analysis showed no dependence of the injuried cells level on duration of work with radioactive substances and on doses of occupational radiation. Finding was significant increase in lymphocytes radiosensitivity in individuals subjected to occupational radiation. This group appeared to contain the staffers with micronuclear cells share more than 2 times exceeding average values.
