We have been researching the mechanism of the element transport in plants by producing positron-emitting nuclides (¹¹CO₂, ¹³N₂, ¹⁰⁷Cd, etc.) and using a planar-type positron imaging device. Since the Fukushima nuclear accident in 2011, we have been working on the development of positron imaging technology for cesium in plants. In this presentation, I will introduce a new method for purifying ¹²⁷Cs positron-emitting nuclide (half-life: 6.25 hours).
