The influence of leaf feeding with nitrogen in urea solution and application of chlorocholine chloride (CCC) on the uptake of 137Cs by spring wheat from the investigated soil samples and through leaves was studied in pot experiments. Spray application of nitrogenous fertilizer in urea solution with additional use of growth retardant were found to have brought about an increased accumulation in the grain of 137Cs taken up by the plants from the contaminated soil. It was found that 2–4 times more 137Cs accumulated in wheat grain from leaves contaminated in the flowering stage in comparison with that found in the grain of plants contaminated in the propagation stage. The application of leaf feeding with urea and chlorocholine exerted no influence on the accumulation of 137Cs in grain if the plants had been contaminated superficially in their earlier development stages. Contamination with 137Cs sprayed upon the plants after application of chlorocholine chloride appeared to pass to the spring wheat crops more readily.
