| Popis: | Due to their high efficiency and speed of use, alpha scintillation cell is being increasingly utilized for detection of radon (222Rn) in soil gas. The calibration factor of the 110 A active radon cell has been addressed and thoroughly discussed. The sensitivity and the efficiency have been determined. It is found that the sensitivity and the registration efficiency of this scintillation cell (110 A active cell) are equal to 0.015895 cpm/Bq/m3, 59%. Respectively. A nuclear system was adapted to measure the accumulation of radon gas using the active scintillation cell. The growth curves of radon activity have been investigated. Radon emanation, leakage and back diffusion rates from natural occurring radioactive materials has been determined. Compatibility between practical measurements and results based on the theoretical equation were achieved. |
