Times Cited Count:1 Percentile:7.12(Physics, Applied)Radioisotope tracer imaging is useful for studying plant physiological phenomena. In this study, we developed an autoradiography system with phosphor powder (ZnS:Ag), "Live-autoradiography", for imaging radioisotope dynamics in a living plant. This system visualizes the element migration and accumulation in intact plants continuously under a light environment. An imaging test was performed on point sources of Cs, with a radioactivity of 10-100 kBq of being observed; this indicates satisfactory system linearity between the image intensity and the radioactivity of Cs. Moreover, dynamics imaging of Cs was performed on an intact soybean plant for four days. The serial images indicated Cs accumulation in the node, vein, and growing point of the plant. The developed system can be used for studying plant physiological phenomena and can be employed for quantitative measurement of radionuclides.

We have developed a novel technique named projection autoradiography. Charged particles in a magnetic field move spirally following the Larmor precession. By utilizing this phenomenon, it is possible to control the trajectory of beta particles emitted from the sample and project the RI distribution onto the IP. Specifically, a uniform magnetic field is applied between the sample and IP, then the beta particles move spirally toward the IP without the severe deterioration of the sensitivity and resolution. In order to prove the new technique, an autoradiography experiment was performed. This result proved that projection autoradiography technique is promising for various applications, such as direct taking a radiograph of cultured samples in a petri dish, etc.
