In the conditions of the Republic of Belarus there were presented results of development of a system of quantitative parameters, which characterized radiation safety and economic efficiency of agricultural reuse of lands which had been contaminated with radionuclides and had been withdrawn from agricultural production on evaluated lands. The parameters helped to base the possibility of use of a land plot in agricultural production according to its radiological, agronomical and technical characteristics and the distance between the plot and a potential land user. In course of the study there were analyzed the following radiological and economic indexes of feasibility of former contaminated lands: content of 137Cs in soil; content of 90Sr in soil; forecasting of contamination of agricultural products; soil fertility degree; terms of recoupment of capital investments. There were given practical recommendations for growing of cereal grain crops (winter wheat (Triticum aestivum); spring wheat; barley (Hordeum vulgare); field pea (Pisum arvense L.); green pea (Pisim sativum); rape (Brassica napus); and perennial grasses) on the contaminated areas.
