Mapping 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 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 کاملThe 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 کاملAssessment of Temperature-driven Pressure Differences with Regard to Radon Entry and Indoor Radon Concentration
A heavily instrumented and unoccupied research house is used to continuously monitor the temperature in each room, the supply and return ducts, HVAC thermostat location, attic and outdoors. Simultaneous measurements of the differential pressures have been performed across the house walls, indoorfattic zones, the house slab and the indoor zones. Indoor radon concentrations and meteorological con...
متن کاملPotential 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...
