Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for soil radon meters, specifically, it is a portable soil radon meter gas filtration and drying device. Background Technology

[0002] Radon detectors have wide applications in various technical fields, including geological exploration, radiation protection, nuclear accident monitoring, radiation dose assessment, earthquake prediction, and teaching research. They can determine the activity concentration of the radionuclide radium-226 in media such as water, rocks, and soil. The working principle involves a pump system introducing the radon-containing gas to be measured into a scintillation chamber. During the alpha decay of radon-226 and its decay products, alpha particles released interact with the ZnS(Ag) fluorescent coating on the inner wall of the scintillation chamber, producing characteristic fluorescence. This fluorescence signal is converted into an electrical pulse signal by a photomultiplier tube. By measuring the pulse count rate per unit time, a quantitative relationship with the radon concentration can be established, thus achieving accurate radon concentration determination. In soil radon content measurement, a specialized sampler must be vertically inserted 60–80 cm below the ground surface to collect radon samples. The radon sample must be dust-free and water-free to ensure the accuracy and representativeness of the measurement results.

[0003] Chinese patent CN216909518U discloses an auxiliary gas-liquid separator for a soil radon meter. By setting built-in air inlet and outlet pipes at different heights on a cylindrical barrel, the gas-liquid mixture is drawn into the cylindrical barrel from the air inlet pipe, which is lower than the outlet pipe. Liquid water is stored in the lower part of the cylindrical barrel, and the gas to be tested is stored in the upper part of the cylindrical barrel, thus completing the gas-liquid separation.

[0004] As described in the above technical solution, the inventors discovered that the root cause lies in the difficulty of cleaning the cylindrical container when the air inlet pipe draws in a gas-liquid mixture. The liquid is typically muddy water, and the dried muddy water generates a large amount of dust. Upon reuse, this dust is easily drawn into the radon meter, causing damage. Furthermore, when the groundwater pressure in the measurement area is abnormal, the gas-liquid mixture is easily drawn into the radon meter, leading to instrument damage. In field use, its lightweight and low stability make it prone to tipping over, causing experimental interruptions, increasing time and labor costs, and affecting work progress. To solve these technical problems, it is necessary to provide a portable soil radon meter gas filtration and drying device. Summary of the Invention
