Effect of treatment time on the 134Cs and 85Sr concentrations in green bean plants

Green bean plants were sprayed with 85Sr and 134Cs at three different growth stages; 4 h after each treatment, half of all treated plants were sprinkled; at harvest, pod and leaf activity were detected. Results indicate that treatment time has an important role in the concentration of radionuclides in both sprinkled and non-sprinkled plants. Furthermore sprinkling reduces 134Cs and 85Sr concentrations, since the three growth stage reductions were 65, 60 and 52% for 124Cs, and 24, 39 and 58% for 85Sr.
