Abstract

It is shown that the use of mineral fertilizers in areas contaminated with radioactive cesium has a radio-ecological specificity, caused by the need to obtain the guaranteed normatively safe agricultural product. The radiological effectiveness of mineral fertilizers is differentiated depending on the belonging of plants to different biological species. In conditions of sod-podzolic soils of Polissya it is much higher than on chernozems.

Highlights

IntroductionOne of the characteristic features of the remote period of radiation situation development after radionuclide contamination of the environment due to nuclear and radiation accidents and incidents is that the main way of radionuclide inclusion into food chains is its root intake from soil into plants [1, 2], and internal irradiation prevails in the structure of total population exposure dose - with food products produced on radioactively contaminated territories [1, 3]
The development of a set of measures aimed at obtaining guaranteed radiation safe products necessarily takes into account the soil-agrochemical features of the contaminated territory [7], and the study of soil-agrochemical aspects of the criticality of radioactively contaminated agricultural landscapes remains an important and relevant task in the distant period of radiation situation development after localization of nuclear and radiation accidents and incidents
It is known that radiation-ecological approaches to determination of soil criticality degree in the distant period after the Chernobyl catastrophe are largely determined by its type and potential fertility [9. 10, 11]
