Показано, что динамика средних значений эффективной дозы внешнего облучения жителей в этот период времени после чернобыльских выпадений хорошо описывается процессами, учитывающими радиоактивный распад и естественную миграцию радионуклидов цезия. Распределение индивидуальных доз внешнего облучения жителей населенных пунктов, нормированное на среднее значение дозы в населенных пунктах, соответствует логарифмически нормальному закону с устойчивыми во времени параметрами: геометрическим средним значением ~ 0,9 и геометрическим стандартным отклонением ~ 1,5, что позволяет, в частности, прогнозировать значение дозы у критической группы населения или для репрезентативного индивидуума (a representative person). Сравнение значений средних эффективных доз внешнего облучения у жителей населенных пунктов, оцененных на основании результатов двух различных методов измерений (индивидуальных доз с использованием термолюминесцентных дозиметров и измерений мощностей доз в воздухе в различных локациях населенных пунктов), показало их хорошее согласие через 17 лет после аварии. В двух населенных пунктах, где проводились измерения в 2003 г., относительные различия значений средних эффективных доз не превышали 12%. Это позволяет и в дальнейшем использовать ранее разработанную модель внешнего облучения для оценки доз у населения, проживающего на территориях, загрязненных вследствие чернобыльской аварии.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents an analysis of the dynamics of individual doses of external exposure among the population living for almost 20 years in the territories affected by the radioactive contamination due to the Chernobyl NPP accident. The dynamics of the average effective dose of the external exposure of the inhabitants in the period of 5 to 20 years after the Chernobyl fallout is well described by processes that consider the radioactive decay of cesium radionuclides and their natural migration. The distribution of individual doses of external exposure among residents, normalized to the average dose in the settlement corresponds to a logarithmically normal law with the time-stable parameters: the geometric mean ~ 0.9 and geometric standard deviation ~ 1.5, which allows, in particular, predicting the dose for the critical group of population or for a representative person. Comparison of the mean effective doses of external exposure of the settlement residents estimated based on the results of two different measurement technologies (using TLD-method and measurements of dose rates in air in various settlement locations) indicated their good agreement for the 17 years period after the fallout. For two settlements, where measurements were performed in 2003, the relative differences in mean effective doses did not exceed 12%. It allows using the previously developed model of external exposure for dose estimation to the population residing on the territories contaminated after the Chernobyl accident.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>чернобыльская авария</kwd><kwd>внешнее облучение населения</kwd><kwd>эффективная доза</kwd><kwd>мощность дозы гамма-излучения</kwd><kwd>термолюминесцентные дозиметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chernobyl accident</kwd><kwd>external exposure of people</kwd><kwd>effective dose</kwd><kwd>gamma-radiation dose rate</kwd><kwd>thermoluminescent dosemeters</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Erkin, V.G., Lebedev, O.V.
