Study on the effect of air purifier for reducing indoor radon exposure

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