抄録

<p>The metal fiber filters and silver zeolite (AgX, etc.) that have a proven track record in Filtered Containment Venting System(FCVS) are nonflammable and can be used even at high temperatures. And also scrubbing technology is greatly improve the decontamination factor (DF) of radioactive substances. By applying these technologies, we propose to make the air purification system more robust and smaller, and making it mobile. The system is expected to be used in a wide variety of ways such as by moving to an emergency evacuation site or a highly polluted place in the event of an accident to supply clean air for reducing the exposure of local residents and radiation workers. We manufactured the prototype of portable air purification system in 2020. Performance tests such as DF tests were conducted in 2021. As a result, we confirmed the high adsorption performance of organic iodine and the high collection rate of barium sulfate.</p>
