【Abstract】 Indoor air was first collected by cylindric plexiglas-scintillation bottle. When radon in the bottle is equal to radon and its product in air, the density of random is detected by detector point and survey system. The results showed that the method was simple and had reliable function and high sensitivity. Accuracy and precision of the method met hygienic analysis standard.更多还原
