Abstract

Real-time detection of X/gamma radiation dose rates holds particular significance in nuclear science research. In this study, we developed a portable X/gamma-ray survey meter for large-scale distributed real-time monitoring of ambient dose equivalent rates in the surrounding environment. This innovative device uses a silicon photomultiplier coupled with a CsI(Tl) scintillator and can connect to an Internet of Things network. Additionally, it facilitates a wide spectrum of dose rate measurements by modifying the frequency of a pulse-frequency modulation-type DC-DC power supply mode. The energy response of the survey meter, which is improved through Geant4 simulations and a multi-comparator design, ranges from 48 keV to 1.3 MeV, encompassing various common protection level applications. It effectively measures gamma radiation dose rates ranging between 0.1 µSvh^-1 and 100 mSvh^-1 for ⁶⁰Co. Temperature compensation of the detector was achieved through a series of experiments. The meter exhibits a deviation of –25 % to +25 % at temperatures between –40 °C and +40 °C.
