Potential health effects of indoor radon exposure.
Radon-222 is a ubiquitous noble gas arising from decay of radium-226 normally present in the earth's crust. Alpha radiation from inhaled short-lived daughters of radon readily irradiates human bronchial epithelium, and there is now good evidence of excess risk of lung cancer in underground miners exposed to higher concentrations. In homes, radon levels are highly variable, showing approximately...
متن کاملMapping geogenic radon potential by regression kriging.
Radon ((222)Rn) gas is produced in the radioactive decay chain of uranium ((238)U) which is an element that is naturally present in soils. Radon is transported mainly by diffusion and convection mechanisms through the soil depending mainly on the physical and meteorological parameters of the soil and can enter and accumulate in buildings. Health risks originating from indoor radon concentration...
متن کاملMapping the geogenic radon potential in Germany.
Mapping the geogenic radon potential in Germany is a research project initiated by the German Federal Ministry for the Environment, Conservation and Reactor Safety. The project was aimed to develop a standard methodology for the estimation of a geogenic radon potential and to apply this method to map the region of Germany as an overview for planning purposes. The regionalisation results from a ...
متن کاملPotential Radon Release during Fracking in Colorado
Hydraulic fracturing or 'fracking' has become the industry standard for oil and gas production in the United States. The process entails fracturing large sections of rock with high pressure to release oil and gas reserves and to produce conduits for these fluids to flow more easily to the surface. Along with the intended natural gas, water, or any other fluids or other substances that might be ...
متن کاملLung Cancer Risk Attributable to Indoor Radon in a High Radon Potential Region of France
Awareness of the health risks due to exposure to indoor radon has raised concern about its impact in the general population. Using all available epidemiologic results, our goal is to accurately estimate this risk based on data collected in a high radon potential region of France (Franche-Comté). For this study, we considered exposure (response relations derived from cohorts of miners and from j...
