Experimental Determination of the Effectiveness of Radon Barriers
نویسندگان
چکیده
Several types of membrane materials (radon retarders) are available for placement under concrete slabs as barriers to the upward movement of soil gas into buildings. Selection of barrier material is seldom based on its resistance to air permeation, as such information is not readily available. For the current study, the permeability of several membrane materials, which may be used as radon barriers, were tested in the laboratory using three methods. All membrane materials were found to significantly reduce radon permeation, but the efficacy of resistance varied considerably amongst the membranes.

متن کاملDetermination of Radon Level in Drinking Water in Mehriz Villages and Evaluation the Annual Effective Absorbed Dose
Introduction: Radon is one of the most radioactive elements that may be found in soil, air and water naturally. Presence of fault and also granitic rocks near the water sources can cause high radon levels in these water resources. Radon concentration of various drinking water sources And network In Mehriz Villages was measured from Anar- Mehriz fault and granite stone of Shirkooh area. Materia...
