Radon is a noble gas, which endangers our health. The liquid scintillator is one of the detector materials used to measure radon in the environment. But there are challenges in measuring radon using a liquid scintillator, such as independent manual operation and long measurement periods. We propose a liquid scintillator detector for the rapid measurement of radon, which is composed of a breathable liquid scintillator probe and photomultiplier tube. Cascade decay recognition and pulse shape discrimination (PSD) were used to select radon events.
