Abstract

This article gives an analysis of changes in the external dose gama-radiation in forest plantations of the Republic of Belarus with different partial contribution of the various gama-emitting radionuclides. The long-term dynamic, of the external dose gama-radiation in the range of the groups of objects, is determined by the partial contribution of radionuclides with different half-lifes, and approximated by a two-component exponential dependence. The author distinguishes two periods in the dynamics of the dose rate. During the first 5-7 years of external dose gama-radiation were being decreased more rapidly, and since the mid of 90's during half-time external dose gama-radiation is amounted about 20 years.

Key words
Dose, radionuclides, gamma-irradiation.
