Abstract

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.

Keywords: Air purifier; Attached radon decay products; Radon; Unattached radon decay products.
