We updated our imaging system, namely real-time radioisotope imaging system (RRIS) to observe 32 P movement in large plants using a large size scintillator. In the previous version of RRIS, the view was limited by the size of a CsI (Tl) scintillator deposited on a fiber optic plate (FOS). However, owing to the high price and difficulty in handling of FOS, the view area was limited to 100×200 mm. In this study, we evaluated 5 large and low-cost plastic scintillators and showed that plastic scintillators can be used in RRIS for the quantitative analysis of 32 P. We also evaluated the resolution of the imaging system with plastic scintillator.
