초록
In the present study, we developed a real-time radiation-monitoring sensor for an underwater radiation-monitoring system and evaluatedits effectiveness using reference radiation sources. The monitoring sensor was designed and miniaturized using a silicon photomultiplier(SiPM) and a cerium-doped-gadolinium-aluminum-gallium-garnet (Ce:GAGG) scintillator, and an underwater wirelessmonitoring system was implemented by employing a remote Bluetooth communication module. An acrylic water tank and referenceradiation sources (137Cs, 90Sr) were used to evaluate the effectiveness of the monitoring sensor. The underwater monitoring sensor’sdetection response and efficiency for gamma rays and beta particles as well as the linearity of the response according to the gammarayintensity were verified through an evaluation. This evaluation is expected to contribute to the development of base technology foran underwater radiation-monitoring system.
