ABSTRACT
The effects of a simultaneous application of KCl and lime on the root uptake of $^{54}Mn,;^{60}Co,;^{85}Sr;and;^{137}Cs$ by rice, soybean, Chinese cabbage and radish were investigated through 2 years' greenhouse experiments. At their early growth stages, a mixed solution of the radionuclides was applied to the water or soil surfaces of the culture boxes filled with an acidic loamy-sandy soil for the upper 20cm and $83g/m^2$ of fertilizer KCl and $200g/m^2$ of slake lime were applied to the surfaces. Distribution of radioactivities among plant parts and change in uptake pattern with plant species were not, on the whole, significantly affected by the application. It reduced effectively soil-to-plant transfer factors of $^{85}Sr;and;^{137}Cs$ for rice, of all for Chinese cabbage and of $^{54}Mn,;^{60}Co,;and;^{137}Cs$ for radish without their growth inhibition. In rice, $^{85}Sr$ showed the highest decrease $({sim}60%)$ while, in Chinese cabbage and radish, $^{54}Mn$ did $({sim}80%)$. The exprimental results can become valuable reference data to establish countermeasures against a radioactive contamination of farm-land during plant growth.
