摘要：

The absorbed dose rate of external γ-radiation from two sources of radiation – surface soil layer and subsurface phytomass of plants in stand grass – is calculated by different methods. The calculation of the absorbed dose rate based on integration of the dose attenuation function of a point source taking into account the dose accumulation factor was compared with the results of a Monte Carlo solution of the radiation transfer equation (MCNP5 code system). The obtained results show that the absorbed dose rate of external γ-radiation in the air-plant medium can be calculated by integrating the dose attenuation function of a point source with variable radionuclide activity and biometric parameters of the plants.
