Research Abstract |
This study is aims to develop a live-imaging method which visualizes radiocesium movements and distribution from soil to a living plant for agricultural studies such as the control of radiocesium transport into plants. In this study, a "rhizobox" specially designed for the imaging experiments was developed. This rhizobox reproduced the polluted soil environments and grew plants properly. Combining this rhizobox with radioisotope (RI) measuring techniques, I developed a new "RI imaging method" to visualize the dynamics of radiocesium in soil and plants. Furthermore, we developed a positron-emitting radiocesium, 129Cs, in order to visualize radiocesium dynamics using the positron-emitting tracer imaging system (PETIS). These techniques can be widely applied to safety evaluation of food and agricultural products, to selection of agricultural crops which take up high or low radiocesium, and to studies of the optimum cultivation conditions which prevent plants from taking up radiocesium.
