Estimates of doses of internal alpha-irradiation of uranium mining enterprise personnel by using EPR spectroscopy of tooth enamel

Abstract

This article is devoted to the topic of dissertational research for the PhD degree of a doctor in the specialty "Nuclear Physics". In the article the significance and contribution of internal alpha irradiation as an integral part of radioactive
irradiation is pointed out, as well as one of the methods relating to the retrospective estimation of the individual dose-EPR spectroscopy by tooth enamel. The purpose of this article is to describe the possibility of obtaining data by the selected method for determining the radiation impact on personnel of a uranium mining enterprise. Evaluation of the retrospective (related to the past) dose for personnel of the uranium mining enterprise is an urgent issue, as it is necessary to assess the risks of radiation exposure, in order to predict the medical consequences of radiation exposure. Alpha is a heavy particle, but has a small penetrating power. However, the greatest danger to human health is internal irradiation. The fact is that radiation has a powerful energy impact on organs and tissues, which leads to destruction, mutation and degeneration. Therefore, the assessment of doses of internal alpha radiation is a priority.
