title: [Forecast of collective radiation dose decrease of the population of Belarus as the result of optimization of moveable potassium contents in soils contaminated by 137Cs].
abstract: Results of study on an efficiency of potassium moveable content for decrease of a collective dose from 137Cs to the population of Belarus are presented. On the basis of the "cost-benefit" analysis it is shown, that expenses for decreasing averted collective dose due to increase of potassium contents on arable lands amounts to more than 80 thousand US dollars per 1 man.-Sv depending on density of soil contamination of rural districts by 137Cs. It is found that high effect (costs less than 40 thousand US dollars per 1 man.-Sv on hectare of arable land) on averted collective dose from 137Cs at cultivation of cereals can be expected at an optimization of mobile potassium contents in sod-podzolic loamy sand soils with density of 137Cs contamination more than 925 kBq/m2, sand soils--more than 1184, light loam soils--more than 629 kBq/m2.
