The effect of soil texture on the level of 137Cs accumulation by aboveground plant’s phytomass in a pot experiment has been studied. Ryegrass (Lolium multiflorum L.), winter rye (Secale cereale L.) and cucumber’s fruits (Cucumis sativus L.) had highest 137Cs transfer factors 0.61–0.77; 0.54 and 8.5 when grown on loamy sand soil. The highest 137Cs output from soil as % of its total soil content for ryegrass and winter rye were found on loamy sand soil – 0.39 and 0.23% correspondingly. Cucumber plants (fruits) showed the highest 137Cs output on peat and loam soils – 3.41 and 3.02% respectively.
