Модель для оценки и прогноза текущих и накопленных доз внутреннего облучения, сформированных с 1987 г. У населения республики Беларусь

Abstract

Objective: to develop a mathematical model for assessment and prediction of current and accumulated internal irradiation doses in the population since 1987 by WBS-measures. Material and methods. The results of the WBS-measures taken from the RRCRM&HE Data Base were analyzed. The method included selection of the statistically reliable average values of internal irradiation doses in a settlement. A value of the mentioned dose was set as a factor for unknown dependences. Results. The experimental data of the dose time dynamics were approximated with a mathematical model as a sum of two-exponents reflecting different regularities of internal irradiation dose forming over different periods after the disaster. Conclusion. The developed model has a relatively high coefficient of correlation with experimental dependences 0.78-0.88, which makes it possible to use it with less cost and acceptable accuracy for development of the Dose catalogue.

Цель: разработка математической модели для оценки и прогноза текущих и накопленных доз внутреннего облучения населения по результатам СИЧ-измерений с 1987 г. Материалы и методы. Исследовались результаты СИЧ-измерений из Базы данных РНПЦ РМиЭЧ. Метод включал отбор статистически достоверных средних значений дозы внутреннего облучения в НП. В качестве фактора для получения искомых зависимостей была определена величина приведенной дозы. Результаты. Экспериментальные данные динамики дозы во времени были аппроксимированы математической моделью в виде суммы двух экспонент, отражающей различные закономерности формирования дозы внутреннего облучения в различные периоды времени после аварии. Заключение. Разработанная модель имеет достаточно высокий коэффициент корреляции с экспериментальными зависимостями: 0,78-0,88, что позволяет использовать ее с меньшими затратами и приемлемой точностью для разработки Каталогов доз.
