The role of natural ventilation on reducing indoor radon concentration
Due to the increasing of closed ventilation systems used in buildings, the risk of indoor radon is increased day by day. In this study, we selected two sample rooms to calculate the radon emission coefficient from different levels, radon concentration measured when the natural ventilation was completely closed and compared with the analytical results. The results clearly show the difference in ...
متن کاملInvestigating Indoor Radon Concentration Using CR-39 Detector; a Case Study of Gachin Dwellings in Hormozgan
Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...
متن کاملActivity of Ultrafine Fraction of Radon Progeny in Indoor Air
Inhalation of Rn progeny has been recognized as a health risk, primarily as a cause of human lung cancer. Rn progeny in the domestic environment contributes the greatest fraction of the natural radiation exposure to the public. The ultrafine activity of these progeny amounts up to about 10 percent of the total activity (attached and ultrafine), but is considered to yield about 50 percent of the...
متن کاملIndoor radon measurements in residential dwellings in Qom, Iran
Background: Inhalation of radon and its short-lived decay products is one of the ‎most significant sources of exposure to natural radiation. Radon is the second cause ‎of lung cancer in the populations. The present study was carried out under the projects of ‎national radon, with the aim of determining the concentration of indoor in the city of Qom ‎located in the central se...
