Abstract
For neutron detection and radioactive gas sensing, it is greatly beneficial to detect alpha (alpha) particles and gamma rays. In the present work, continuous passive radon detector (CPRD) has been constructed with native ZnS; AgCl scintillator. The detector has been supplied with highly efficient native nano particles scintillator for detection of alpha particles. One of the features of this scintillator, the energy resolution is comparable with or even better than commercial ZnS (Ag) scintillator. This study provides an alternative for the fabrication the native scintillator in the absence of costly scintillator available in the market. Moreover, results of scintillation characteristics, along with physical properties of the scintillator, are addressed and thoroughly discussed. For calibration, radon calibration system with dual radon monitor has been constructed in Najran University, Saudi Arabia. The experimental sensitivity of the passive CPRD cell for radon gas detection was constant with well-known data already published in the literatures. Radon emission from a natural sample has been measured by the fabricated CPRD cell.
