[Does Radioecological Paradox Exist?].

In some cases radioresistant species of plants in radionuclide-contaminated areas have more strong radiation damages than radiosensitive ones. This effect was called "the radioecological paradox". It could be explained by different abilities to accumulate main dose forming radionuclides. It leads to formation of higher doses due to internal irradiation. In the case of the Chernobyl N PP accident it can be conditioned by species specific particularities in consumption of potassium and calcium, and cesium and strontium, correspondingly.

Effectiveness of Protective Activities for Rehabilitation of the Forage Lands in Russia and Belarus Contaminated as a Result of the Chernobyl Accident.

Regularities of changes in the content of (137)Cs in green fodder during the remote period after the CNPP accident depending on application of agro-technical and agrochemical activities are analyzed. It is revealed that the use of mineral fertilizers reduces receipt of (137)Cs from the soil to forage and further to a food chain. It is also established that agrochemical activities are more effective than agro-technical ones.
