Study of annual effective radiation doses of Polesie State Radiation and Ecological Reserve staff

Abstract: Objective. To analyze annual effective radiation doses of the Polesie State Radiation and Ecological Reserve (PSRER) staff over a period of 2021-2022, and identify the factors causing differences in these indicators among various categories of enquired personnel. Materials and methods. The results of 840 measurements of external and internal radiation doses (obtained respectively by the method of thermoluminescent dosimetry and based on WBC measurements) for the period from 2021 to 2022 were studied. Professional, gender and age differences in personnel radiation dose were specified using nonparametric statistics methods by comparing two independent samples, as well as using one-way analysis of variance. Results. The median annual effective dose of radiation for PSRER employees was 1.14 mSv/year in 2021-2022. The highest value of external radiation dose is typical for forestry workers, it is statistically significantly higher compared to executives (p<0.05), specialists (p<0.05), workers (p<0.05), service personnel (p<0.05), drivers (p<0.05), engineers (p<0.05) and researchers (p<0.05). The age factor has a significant impact on dose indicators: for workers aged 59–72 years, the parameters of the annual effective dose are the highest and significantly exceed the doses of workers aged 18-26 years (by 29%) (p<0.05). Higher annual effective dose rates were found in men compared to women (1.2 times, p<0.05). Conclusion. Analysis of radiation doses on employees of the PSRER made it possible to reveal the greatest influence of professional and gender factors on the annual effective dose and effective external exposure dose
