Abstract

Objective: the research is to determine the main radiation-hygienic factors influencing the formation of radiation doses among the population of radioactively contaminated territories (RCT) in Zhytomyr region in 2024 and to analyze the dynamics of internal radiation doses based on original experimental studies conducted in reference settlements from 2012 to 2024.

Materials and methods: In 2024, a comprehensive radiation-hygienic monitoring program was conducted in 11 settlements of Narodychi Territorial Community (TC): the Narodychi and the villages of Selets, Bazar, Rudnya Bazarska, Khrystynivka (Zone 2), Motiyki, Zalissya, Davydky, Radcha, Nova Radcha, and Grezlya (Zone 3). The comprehensive radiation-hygienic monitoring included the following activities: mobile WBC monitoring: 817 measurements (562 adults and 255 children); collection and analysis of food samples: 39 milk samples, 61 potato samples, and 57 samples of wild foods, analyzed for radionuclide content, including 137Cs and 90Sr; assessment of external radiation exposure in these settlements; surveys: 194 individuals were surveyed regarding the consumption volumes of locally produced foods from their own households and purchased foods from commercial networks. The study utilized dosimetric, radiochemical, and mathematical methods of analysis.

Results: The dynamics of internal exposure levels indicate a continued decrease in annual doses for residents of reference settlements, showing a 1.3-2.4-fold reduction compared to 2021 results. In 2024, the annual effective doses are primarily formed by internal exposure, not exceeding 1.04 mSv·year-1 in adults and 0.15 mSv·year-1 in children, under the RCT criterion of 1 mSv·year-1. Survey results show that the most consumed food products among residents of the surveyed settlements are dairy and vegetable products from household farms, as well as baked goods and flour-based products from the retail network. The most contaminated products with 137Cs are wild forest products, particularly berries and mushrooms. Milk from household or local farms is the second-largest contributor to internal exposure doses.

Conclusions: The investigation into the formation of internal radiation doses revealed that the primary contributor to internal exposure for residents of the surveyed settlements in the Zhytomyr region remains the intake of 137Cs through forest products and milk.

基于辐射卫生综合监测的日耳摩铃地区放射性污染区人群剂量形成研究。
目的:研究日托米尔地区放射性污染地区(RCT)人口在2024年辐射剂量形成的主要辐射卫生因素,并在2012 - 2024年参考住区原始实验研究的基础上,分析其内部辐射剂量的动态变化。材料和方法:2024年,在Narodychi领土社区(TC)的11个定居点(Narodychi和Selets、Bazar、Rudnya Bazarska、Khrystynivka村(第2区)、Motiyki村、Zalissya村、Davydky村、Radcha村、Nova Radcha村和Grezlya村(第3区))开展了一项综合辐射卫生监测计划。综合辐射卫生监测包括以下活动:移动WBC监测:817次测量(562名成人和255名儿童);收集和分析食品样品:对39份牛奶样品、61份马铃薯样品和57份野生食品样品进行放射性核素含量分析,包括137Cs和90Sr;评估这些住区的外部辐射照射情况;调查:对194名个人进行了调查,了解他们从自己的家庭和从商业网络购买的当地生产的食品的消费量。该研究利用了剂量学、放射化学和数学分析方法。结果:内部暴露水平的动态表明,参考住区居民的年剂量持续下降,与2021年的结果相比减少了1.3-2.4倍。2024年,年有效剂量主要由内照射形成,在RCT标准为1毫西弗·年-1下,成人不超过1.04毫西弗·年-1,儿童不超过0.15毫西弗·年-1。调查结果显示,被调查居民点居民消费最多的食品是来自家庭农场的乳制品和蔬菜产品,以及来自零售网络的烘焙食品和面食产品。受137Cs污染最严重的产品是野生森林产品,尤其是浆果和蘑菇。来自家庭或当地农场的牛奶是体内暴露剂量的第二大来源。结论:对内辐射剂量形成的调查表明,日托米尔地区被调查居民点居民内照射的主要来源仍然是通过林产品和牛奶摄入的137Cs。
