The alpha dose per unit radon daughter exposure in mines and homes is comparable at about 5 mGy/WLM. This means that excess lung cancer risk determined in follow-up studies of miners should be valid to extrapolating to environmental populations. There are several models currently used for risk projection to estimate lung cancer in the U.S. from indoor radon exposure. The accuracy of the estimat...

Radon is a natural gas known to be the main contributor to natural background radiation exposure and second to smoking, a major leading cause of lung cancer. The main source of radon is the soil, but the gas can enter buildings in many different ways and reach high indoor concentrations. Monitoring surveys have been promoted in many countries in order to assess the exposure of people to radon. ...

Abstract Radon is a natural radioactive gas that may cumulate in indoor environments. The impacts of weather events on radon concentration had been explored different places around the world but only marginally Switzerland. Using basic statistical analysis, this study investigates meteorological parameters’ influence concentrations and shows outdoor air temperature most influential beyond other...

Purpose: İzmir is the province of Turkey with highest lung cancer incidences for males, therefore a comparative study was performed in particular districts 2013. In study, it aimed to assess association between risk and indoor radon. 
 Methods: Patients diagnosed 2010 2011 were selected from database Izmir Cancer Registry (ICR). Measurements radon concentrations total 117 locations using S...

The Ohio Radon Information System (ORIS) internet site at http://www.uioledo.edu/-aprs/oris/ is one of the most comprehensive sites on indoor radon available on the World Wide Web. It was developed by the authors under a research grart from the Ohio Department of Health and U.S. Environmental Protection Agency. It is estimated that from 700 to 1300 people die annually in Ohio from radoninduced ...

Radon is a naturally occurring radioactive gas that originates from the decay of uranium in rocks and soils and is linked to some 13% of lung cancer cases in Ireland. Between 1992 and 1999, the Radiological Protection Institute of Ireland (RPII)1 carried out a National Radon Survey (NRS) of Ireland to identify the areas of the country most at risk from high indoor radon levels. Those areas wher...

The highest time-averaged indoor radon concentrations for a slab-on-grade structure occur when the structure experience neutral pressure conditions. Experimental evidence was provided throughout the utilization of the University of Florida Radon Research House (UFRRH) showing that semi-diurnal atmospheric pressure variations are responsible for continuous pumping of radon-rich soil gas into the...

There are many indoor pollutants in the residential buildings. Of those radon is a major and harmful indoor pollutant in most countries. Radon sometimes entries to the house through building materials. High insulation and tightness in order to increase energy efficiency and to lower energy costs is led to the indoor air quality problems. Ventilation is a good method to dilute radon contaminant ...

Can a significant number of radon-related lung cancers be averted by mitigating existing single-family houses whose radon is above the action level? Would societal resources be used cost effectively by a comprehensive measurement and mitigation policy using the existing or some other radon action level? Simple questions, complex answers. The risk of lung cancer depends on the radon exposure in ...
