Abstract
Relevance. There is a need to evaluate doses retrospectively in Chernobyl nuclear power plant accident recovery workers without established external doses.Intention: To assess the ability of cytogenetic analysis to estimate external radiation doses retrospectively in Chernobyl nuclear power plant accident recovery workers exposed to low-dose radiation in the remote period.Methodology. Cytogenetic biological indication and biological dosimetry were performed in Chernobyl nuclear power plant accident recovery workers 27–30 years after their participation in recovery works. Stable and unstable chromosome aberrations were assessed in peripheral blood lymphocytes.Results and Discussion. The analysis of unstable chromosome aberrations showed that 45.1 % of Chernobyl nuclear power plant accident recovery workers had radiation markers more frequently than in the comparison group. Biological doses were retrospectively evaluated in 18 % of Chernobyl nuclear power plant accident recovery workers and ranged within 14–48 cGy. Specific anamnestic factors should be assessed while evaluating doses retrospectively.Conclusion. Analysis of stable chromosome aberrations allows retrospective dosimetry after low-dose exp sure if external dose is unavailable. Based on this, adverse health effects of low-dose exposure can be assessed and reimbursed in Chernobyl nuclear power plant accident recovery workers.
