Verification of the Mathematical Model for Calculating the Irradiation Dose from a Radioactive Cloud of Arbitrary Shape Taking Account of Screening by Buildings

Resumo

A three-dimensional code for calculating the dissemination of radioactive contamination in the presence of industrial buildings is being developed at IBRAE RAN. The irradiation dose near an object, including the dose from a radioactive cloud, is calculated on the basis of modeling. The calculation is conducted taking account of radiation screening by buildings. This work is devoted to the verification of the computational method. Calculations of two tests are presented: with and without a screening obstacle. It is concluded that the accuracy of the method, incorporated into the three-dimensional computational code, is adequate.
