A three-dimensional code for calculating the propagation of radioactive contamination under conditions of industrial development in the presence of atmospheric emissions is being developed at IBRAE RAS. The effective irradiation dose rate from a cloud, contaminated soil, and building walls is calculated on the basis of modeling. The screening of ionizing radiation by building walls is taken into account. The present work is devoted to verifying a method of calculating the effective irradiation dose rate due to contaminated soil and building walls. Two test problems are examined: with the contaminated surface of a cone-shaped building and a section of soil. It is concluded on the basis of the solution of problems that the accuracy of the method used in the three-dimensional computational code is acceptable.

计算受污染土壤和建筑物墙壁有效辐射剂量率的数学模型验证

IBRAE RAS 正在开发一个三维代码，用于计算工业发展条件下存在大气排放的放射性污染的传播。来自云、受污染土壤和建筑物墙壁的有效辐射剂量率是在建模的基础上计算出来的。考虑到建筑墙体对电离辐射的屏蔽。目前的工作致力于验证一种计算由于污染土壤和建筑物墙壁引起的有效辐射剂量率的方法。检查了两个测试问题：锥形建筑物的受污染表面和一段土壤。在解决问题的基础上得出结论，该方法在三维计算代码中的精度是可以接受的。
