摘要：

Increasing the gas sampling amount is necessary to solve the substantially higher lower detection limit of radioactive inert gas monitoring in nuclear facilities in China than its actual sampling activity. A nitrogen and oxygen separation membrane is selected to design and set up a set of experimental devices for xenon separation and enrichment to improve radioactive xenon isotope in the airborne effluent. The concentration effect of xenon in the air was tested under different sampling multiples. The gas film enrichment effect of xenon in the air was studied by comparing the sampling multiples, and the influence of the lower detection limit in the onsite sampling laboratory analysis was theoretically calculated. Results showed that by using the air film separation technology, the amount of radioactive xenon sampled in the airborne effluent can be increased to approximately 15 times, thereby reducing the detection limit for radioactive xenon by approximately 15 times when the sampling multiple is 124. 2. © 2022 Editorial Board of Journal of Harbin Engineering.
