A radon monitoring system which can simultaneously measure radon concentrations in multiple sites was developed and tested. The system consists of maximum of four radon detectors, fiber optics cables and a data acquisition personal computer. The radon detector uses a plastic scintillation counter which collects radon daughters in the chamber electrostatically. The supplied voltage on the photocathode for the photomuliplier tube(PMT) acts as a electrode for radon daughters. The thickness of the plastic scintillator was thin, 50μm, so as to minimize the background counts due to the eneiromental gamma rays or beta particles. The energy discriminated signals from the radon detectors are fed to the data acquisition personal computer via the fiber optics cables. The system made it possible to measure the radon concentrations in multiple sites simultaneously.
