Problems solved by technology

[0004] This method can accurately measure the content of radon in the environment, but it needs to filter out the influence of radon progeny in the environment in advance
In addition, when measured using this method, polarized water molecules easily interact with positively charged 218 Po effect, making it into neutral particles, reducing the collection efficiency of the system

Description

technical field [0001] The invention belongs to the field of radioactivity detection equipment, and in particular relates to a gas drying device with the function of filtering radon daughters. Background technique [0002] Radon pollution in the environment has become the main source of radioactive pollution. Radon has a strong adsorption capacity and can be absorbed by almost all solids, especially loose porous substances, increasing indoor radiation levels and endangering people's health. In recent years, the measurement of radioactive content of radon in ambient air has received extensive attention. [0003] There are many methods to measure radon in ambient air, and the commonly used method is pump suction electrostatic collection energy spectrum analysis method. This method uses active pumping to suck radon-containing gas into a high-pressure chamber, and the radon gas decays to produce 218 Po positively charged particles are adsorbed to the surface of the detector at...
