The pandemic has increased this figure by hundreds of times, including in children. At the same time, a number of scientific studies have proved the emergence of negative health effects that are directly related to the radiation exposure of patients.</p>
<p>The purpose of the work is to assess the lifetime risk of radiological and radionuclide examinations for different age groups, particularly in children.</p>
<p>The study is based on materials collected at the Voronezh Regional Clinical Consultative-Diagnostic Center. Calculation methods were used to estimate lifetime radiation risk. More precisely the lifetimĕ risk of distant health effects during radiological and radionuclide examinations can be calculated using absorbed doses in certain organs as well as individual tissues and dependence on their sensitivity to radiation and on age based on a linear non-threshold model. In order to assess the justification of the amount of diagnostic information obtained by the amount of prescribed interventions, a study was conducted and an analysis of personal radiation risks in children according to standard indicators such as sex, age, anamnesis, and according to the stage of CT, i.e. the degree of lung damage, was performed. Lifelong radiation risk was calculated using ICRP nominal risk coefficients taking into account age-related radio-sensitivities as well as using a linear nonthreshold model. As a result, it was found that the effective dose in children is twice less than the effective dose in adults, which is of particular importance in assessing radiation risks in children. A particular danger of ionizing radiation is the possibility of further development of stochastic effects; accordingly, the higher the radiation dose, the higher the probability of adverse effects.</p>
<p>As a result of the entire study found that ionizing radiation is a particular danger due to the possibility of further development of stochastic effects, based on the findings, we can conclude that children are many times more exposed to lifetime radiation risk than adults, so the amount of diagnostic should be much greater than the amount of radiation damage received.</p>
<p>In conclusion, we would like to note that the emergence of such a significant volume of conducted lung CTs in children now serves as a starting point for the study and calculation of individual radiation risks in children, as in previous years there were not so many studies.</p>сomputed tomographyradiation riskeffective doselifetime riskкомпьютерная томографияриск радиационныйэффективная дозапожизненный риск[М.И.
