 Abstract

The external radiation doses from the radionuclides commonly found in the natural soil environment were estimated by the application of the following methods: Gamma-radiometry and Monte Carlo calculations using the MCNP code, taking into consideration  the concentrations of gamma emitters in the soil. The calculated results were compared with the experimental data and the results of calculations performed with other analytical methods and were found to be in a good agreement.   

Keywords: External dose rate, gamma emitting radionuclides, gamma radiometry, theoretical estimations, MCNP code.
