Research on the disposal system of radon chamber exhaust gas

Background: The activated carbon sorption is often used to reduce the concentration of the exhaust gas. But the ability of sorption is limited. If the concentration is high, the radioactive pollution may take place at the surroundings of radon chamber. In addition, natural decay of radon takes a long time because of the long half-life of radon. Purpose: The aim is to solve the problem of radioactive pollution and reduce the radon concentration in the radon chamber in a short time. Methods: The aim is to put forward a disposal system to bring the exhaust gas to storage chamber and keep the exhaust gas in the storage chamber for some time then let out. Results: By this way, the radon concentration of radon chamber can be reduced in a short time and the radioactive pollution can be solved. Conclusion: The disposal system can achieve the expected goals. (authors)
