The absorption and dynamics of Cs in crops can be measured and examined using not only137Cs but also133Cs, a stable isotope which can be analyzed in a regular laboratory. When133Cs is used, however, the concentration of added133Cs must be set higher than that in the soil solution due to the detection sensitivity of inductively coupled plasma optical emission spectrometry (ICP-OES). There is concern that such high Cs concentrations may adversely affect crops and interfere with Cs dynamics. Using soybean as a test product, we first examined the initial growth of soybean cultivated under exposure to solutions with different133Cs concentrations. In combination with each133Cs concentration, two potassium (K) concentrations were tested. Results show that at both K concentrations, growth was inhibited under133Cs concentrations higher than 1 × 10−3mol L−1. Soybeans cultivated at133Cs concentrations higher than 1 × 10−6mol L−1can be subject to ICP-OES for measuring133Cs concentrations in the plant tissue. Next, soybeans cultivated under different133Cs concentrations throughout growth were examined for Cs distribution in the plants. The distribution patterns of Cs in soybean plants cultivated at133Cs concentrations equivalent to those found in the soil were almost identical to those in plants cultivated at measurable133Cs concentrations (1 × 10−6–1 × 10−4mol L−1) as measured with ICP-OES. Therefore, in our investigation,133Cs distribution in soybean plants treated with up to 1 × 10−4mol L−1was considered equivalent to that in plants cultivated in the field.
