To elucidate how plants absorb and utilize various elements, we developed a compact multi-point detection system capable of noninvasively monitoring the dynamics of RI tracers at multiple sites within the plant. The system is equipped with 16 high-resolution detectors and supports dual-mode measurement for gamma-ray, beta-ray, and positron-emitting nuclides. We are currently evaluating its performance using various RIs, and in this presentation, we report the results of monitoring carbon translocation to strawberry fruits following ¹¹CO₂ administration.
