Exposure to indoor radioactive gases for long spells increases the risk of health-related issues. The primary mechanism contributing to indoor radon levels is radon transportation, subsequently exhalation from the soil matrix/ building material matrix to the enclosed indoor air of dwellings. Long-term exposure to elevated indoor radon levels may lead to the possibility of health-related problems. The use of Radon Transportation Resistive (RTR) material in the building construction may reduce the indoor radon concentration. The purposes of present study is to investigate the radon diffusion process through the thermocol sheet. This experimental study examined the Thermocol sheet for Radon Diffusion Coefficients (RDC) and Radon Diffusion Length (RDL). The mean RDC and RDL values for the investigated sample were to be (2.56 ± 0.72) x10-8 (m2 . s-1) and 0.10 ± 0.01 (m).

Abstract


Exposure to indoor radioactive gases for long spells increases the risk of health-related issues. The primary mechanism contributing to indoor radon levels is radon transportation, subsequently exhalation from the soil matrix/ building material matrix to the enclosed indoor air of dwellings. Long-term exposure to elevated indoor radon levels may lead to the possibility of health-related problems. The use of Radon Transportation Resistive (RTR) material in the building construction may reduce the indoor radon concentration. The purposes of present study is to investigate the radon diffusion process through the thermocol sheet. This experimental study examined the Thermocol sheet for Radon Diffusion Coefficients (RDC) and Radon Diffusion Length (RDL). The mean RDC and RDL values for the investigated sample were to be (2.56 ± 0.72) x10-8 (m2 . s-1) and 0.10 ± 0.01 (m).
