We investigated the effect of air purifier for reducing the indoor radon exposure by continuously measuring the radon (Rn), attached radon decay products (D^a_Rn) and unattached radon decay products (D^u_Rn). The results showed that the air purifier can effectively reduce the concentration of D^a_Rn and D^u_Rn except Rn. The results showed that the air purifier can be a helpful supplement to the existing radon mitigation methods.

空气净化器降低室内氡暴露效果研究

我们通过连续测量氡 (Rn)、附着氡衰变产物 (D ^a _Rn ) 和未附着氡衰变产物 (D ^u _Rn ) 来研究空气净化器对减少室内氡暴露的影响。结果表明，空气净化器能有效降低除Rn外的D ^a _Rn和D ^u _Rn的浓度。结果表明，空气净化器可以作为现有氡减排方法的有益补充。
