137Cs and 40K uptake by vegetable plants was examined in a number of places in Belarus located at the outer perimeter of the 30-km Chernobyl zone. Differences in the uptake of 40K and 137Cs by plant species were not found to be related to the radionuclide content in the soil, but are essentially related to plant features. Vegetable plants were found to accumulate 40K more actively than 137Cs. For 40K and 137Cs, the ratio of the nuclide content in plants to their content in soil shows a tendency to decrease with increasing nuclide concentration in soil.
Key words: 137Cs / 40K / vegetable plant / uptake / Chernobyl zone
