Rapidly maturing plants were grown simultaneously at the same experimental sites under natural conditions at the Chernobyl Exclusion Zone. Roots of the plants were side by side in the soil. During two seasons we selected samples of the plants and of the soils several times every season. Content of Cs-137 in the plant and in the soil solution extracted from the samples of soils was measured. Results of measurements of the samples show that, for the experimental site, Cs-137 content in the plant varies with date of the sample selection. The plant:soil solution Cs-137 concentration ratio depends strongly on the date of selection and also on the type of soil. After analysis of the data we conclude that Cs-137 plant uptake is approximately proportional to the content of dissolved Cs-137 in the soil per unit of volume, and the plant:soil solution Cs-137 concentration ratio for the soil is approximately proportional to the soil moisture.
