The results of simulation of characteristics of atmospheric ?- and ?-radiation fields due to radioactive decay of soil radionuclides are represented. Monte-Carlo method was used for simulation. Secondary radiation and cascade nature of radiation interaction with air were taking into account. Features in vertical profiles of ? - and ? - radiation absorbed doses and flux densities in ground atmosphere are discussed in detail.

МОДИФИЦИРОВАННЫЙ МЕТОД ГРАНИЧНЫХ ЭЛЕМЕНТОВ ДЛЯ РЕШЕНИЯ ЗАДАЧ КОЛЕБАНИЯ ПЛАСТИН

В.П. Федотов & V.P. Fedotov
This work is devoted to developing algorithms for the solution of wave problems in mathematical physics on the basis of the boundary element method (BEM). The main advantages of the boundary element method is reduced to one dimension of the problem and transfer sample to the boundary of the study area, as well as obtaining a continuous solution in the region. As a consequence, reduces the amount of calculation and improves the accuracy of the...
