翻译后摘要-个人辐照剂量的确定由电子顺磁共振光谱的居民的牙釉质的Zaborie，污染最严重的居住定居点切尔诺贝利事故后没有撤离。使用专门开发的自动光谱处理程序进行剂量测定。在不同的操作模式下进行光谱处理，并取平均结果，以减少光谱处理对剂量确定不确定度的贡献。对牙釉质中确定的吸收剂量进行了校正，以考虑到天然本底辐射的贡献，并确定由于领土的放射性污染造成的个人过量剂量。将个体过量剂量与使用局部放射性污染水平、剂量率和有关个体行为的信息估计的计算的牙齿个体剂量进行比较。通过电子顺磁共振光谱法测量的个体过量剂量和计算的个体化剂量完全独立。发现两种方法的结果之间的均方变异为34 mGy，这与两种方法的误差估计一致。这一结果可以验证这里提出的信号处理的方法，当使用电子顺磁共振剂量测量的牙釉质低剂量和个体化剂量计算的方法。
Abstract— Individual irradiation doses were determined by electron paramagnetic resonance spectroscopy of the tooth enamel of the inhabitants of Zaborie, the most contaminated inhabited settlement not evacuated after the Chernobyl accident. Dose determination was performed using a specially developed automatic spectrum processing procedure. Spectrum processing was carried out in different operating modes, and average results were taken in order to reduce the contribution of uncertainty in dose determination caused by spectrum processing. The absorbed doses determined in enamel were corrected to take into account the contribution of natural background radiation and to determine the individual excess dose due to radioactive contamination of the territory. Individual excess doses are compared to calculated individualized doses to teeth, estimated using the local radioactive contamination levels, dose rates, and information concerning individual behavior. The individual excess doses measured by electron paramagnetic resonance spectroscopy and the calculated individualized doses are fully independent. Mean square variation between results of two methods was found to be 34 mGy, which is consistent with error estimation for both methods. This result can validate both the methodology of signal processing presented here when using electron paramagnetic resonance dosimetry of tooth enamel for low doses and the methodology of individualized dose calculation.
