Atomic energy contributes to environmental conservation with radiation applications as well as nuclear power. Contamination of rice grain by cadmium is one of the major environmental and agricultural problems in Japan. Our group has been elucidating the process of cadmium movement from the soil to the rice grain through the living rice plant using positron-emitting tracer imaging system (PETIS). Based on the results, now we are starting to develop a crop for decontamination of the soil.
