摘要

对于氡室废气的处理，常利用活性炭吸附来降低氡室排放废气的氡浓度，但活性炭的吸附能力有限，当氡室废气浓度较高时会对氡室周围环境造成放射性污染。如果让氡废气在氡室内自然衰变，会因为氡较长的半衰期而耗费时间，造成氡室标定周期长，降低了氡室的利用率。因此提出一种氡室废气处理方案，经过理论分析和实验验证。结果显示，该系统不仅能解决氡室废气排放过程中存在的污染问题，降低对活性炭的依赖；同时能在短时间内降低氡室内氡废气的浓度，缩短废气排放的时长。整个系统的低负压状态也确保了氡室在运行过程中的安全性，因此该氡室废气处理系统实现了预期目标。

Abstract

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. Abstract
