We have developed a monitoring system of $$^{107}$$Cd radioactivity in tracer solution using Positron Multi-Probe System (PMPS) that enables the noninvasive measurement of the amounts of $$^{107}$$Cd uptake by an intact plant. Two-week old oilseed rape plant (${it Brassica napus}$ L.) was placed into a plastic cylindrical container containing 30 ml of 0.5 mM CaCl$$_{2}$$ solution with approximately 10 MBq of $$^{107}$$Cd. The cylindrical container was divided by nylon mesh into two compartments, the root of the plant was immersed in the upper compartment, and a pair of PMPS detectors was placed outside the bottom compartment. As a result, we successfully obtained the continuous data of the amount of a radioactive tracer taken up by the intact plant for 36 hours.
