of this study was to determine the levels of radionuclides in the rescuers' bodies of the SES during firefighting in the exclusion zone of the Chornobyl nuclear power plant and to assess the dose of internal radiation dueto this receipt.
From 06.04.2020 to 19.05.2020 in the State Institution «National Research Center forRadiation Medicine of the National Academy of Medical Sciences of Ukraine» (NRCRM) measurements of the contentof incorporated gamma radionuclides on whole body counters (WBC) operational class «Screener-3M» (Minimumdetected activity (MDA) is 300-500 Bq for 5 minutes of measurement at 137Cs) and expert high-sensitivity WBC (MDAis 20 Bq for 10 minutes of measurement at 137Cs). 470 people (523 measurements) in three groups of personnel ofthe SES of Ukraine who took part in the forest fire liquidation in the exclusion zone in the period from April 4 toMay 5, 2020 were examined. Mathematical and spectrometric methods are used in the work.
In the vast majority (95 %) of the personnel of the SES of Ukraine, examined at the WBCoperational class «Screener-3M» (more than 500 measurements), the assessment of the values of the individualeffective dose of internal radiation due to 137Cs in the body during firefighting, assuming that it receipt occurredduring operation in the exclusion zone, did not exceed the minimum dose detected by MDD (5-14 μSv). The average value of the effective dose of internal radiation in the group of personnel of the State Emergency Service ofUkraine in Kyiv, which participated in the elimination of forest fires in the exclusion zone from April 4 to May 5, 2020(26 people) studied at the expert WBC, is 2.5 ± 1.1 μSv, in the group of personnel of the SES of Ukraine in Cherkasyregion, which participated in the fire on April 19-24, 2020 (9 people) - 2.2 ± 0.6 μSv, in the group of personnel ofthe SES of Ukraine in the Kyiv region, which took part in the elimination of the forest fire in the exclusion zone onApril 4 - May 5, 2020 (42 people) - 4.4 ± 2.4 μSv. Maximum values of 5.1 μSv, 3.5 μSv, 11.8 μSv in the groups ofKyiv city, Cherkasy and Kyiv regions, respectively, which is much lower than the basic dose limit for the populationfrom man-made sources of 1000 μSv · year-1 according to the Law of Ukraine about protection of the person againstinfluence of ionizing radiation.
本研究旨在确定乌克兰紧急事务部门（SES）救援人员在切尔诺贝利核电厂禁区内进行消防行动时体内放射性核素的水平，并评估因摄入这些放射性核素而导致的内照射剂量。
自 2020 年 4 月 6 日至 5 月 19 日，在乌克兰国家医学科学院辐射医学国家研究中心（NRCRM）使用全身计数器（WBC）操作级别的仪器（Screener-3M）（对于 137Cs 的 5 分钟测量，最低检测活度（MDA）为 300-500Bq）和专家级高灵敏度 WBC（对于 137Cs 的 10 分钟测量，MDA 为 20Bq）进行体内放射性核素掺入的测量。共检查了乌克兰 SES 的 470 名（523 次测量）工作人员，他们在 2020 年 4 月 4 日至 5 月 5 日期间参加了禁区内的森林火灾扑灭工作。在这项工作中使用了数学和光谱方法。
在接受乌克兰 SES 工作人员（超过 500 次测量）WBC 操作级别的筛查器-3M 检查的绝大多数（95%）人员中，评估因 137Cs 导致的体内内照射个人有效剂量的个体值在假设它是在禁区内作业期间摄入的情况下，不会超过 MDA 检测到的最小剂量（5-14μSv）。在 2020 年 4 月 4 日至 5 月 5 日期间在专家级 WBC 研究的参加禁区森林火灾扑灭工作的基辅 SES 工作人员（26 人）中，内照射有效剂量的平均值为 2.5±1.1μSv，在参加 2020 年 4 月 19 日至 24 日火灾的切尔卡瑟地区 SES 工作人员（9 人）中为 2.2±0.6μSv，在参加 2020 年 4 月 4 日至 5 月 5 日在禁区扑灭森林火灾的基辅地区 SES 工作人员（42 人）中为 4.4±2.4μSv。基辅市、切尔卡瑟和基辅地区组的最大值分别为 5.1μSv、3.5μSv 和 11.8μSv，远低于乌克兰关于保护人员免受电离辐射影响的法律规定的人口来自人为源的基本剂量限值 1000μSv·year-1。
