The objective of this study is to censure the provision of correct information to the public through investigating radon emanation by building materials that are used in domestic construction environment. Radon emanation has been identified in 10 framing materials and 16 finishing materials of 26 building materials used in the domestic construction-industry. Radon emanation was measured using the closed chamber method based on CR-39 nuclear track detectors(NTDs). On Brick-General in framing materials, the highest radon emanation rates were 0.60028 Bq/ m2·h for surface and 0.00733 Bq/kg·h for mass, while on Ceiling-Tex Cement Plaster in finishing materials. The highest radon emanation rates were 0.47708 Bq/m2·h for surface and 0.05885 Bq/kg·h for mass.
