[Determination of the level of internal irradiation of people farming in territories polluted by radionuclides].
The derived specific activities of radionuclides in the soil are calculated for different pathways of the internal irradiation at a level of an effective dose of 1 mSv per year. The ratio of the actual specific activity to its derived specific activity gives a value of the contribution to annual effective dose for the considered irradiation pathway. The results of the work make it possible to find the upper estimation of the effective dose by simple measurements of the exposure dose rate in a soil sample of a given geometry and by rate of pulses counting by beta- and alpha-radiometry of thick soil samples.
