Mapping Indoor Radon Potential Using Geology and Soil Permeability
نویسندگان
چکیده
The relative potential for elevated residential indoor radon has been mapped for the City of Fort Collins, Colorado. Using published geologic maps and soil permeability information, the study area was divided into geologic and soil permeability (geoperm) units. Evaluation of the data showed a relationship between residential basement indoor radon concentrations and geopenn units. Mean indoor radon concentrations for specific geopenn units ranged from 4.6 to 14.1 picocuries per liter (pCiIL). Using the corresponding indoor radon concentration data, geoperm units were classified into two categories, moderate and high, representing relative potential for elevated indoor radon concentrations. Color coding of mapped geopenn units, according to high or moderate potential for elevated indoor radon concentrations, has been accomplished to create an indoor radon potential map for the City of Fort Collins.

Comparison of Northern Ireland radon maps based on indoor radon measurements and geology with maps derived by predictive modelling of airborne radiometric and ground permeability data.
Publicly available information about radon potential in Northern Ireland is currently based on indoor radon results averaged over 1-km grid squares, an approach that does not take into account the geological origin of the radon. This study describes a spatially more accurate estimate of the radon potential of Northern Ireland using an integrated radon potential mapping method based on indoor ra...
متن کاملUse of a geographic information system (GIS) for targeting radon screening programs in South Dakota
Because (222)Rn is a progeny of (238)U, the relative abundance of uranium may be used to predict the areas that have the potential for high indoor radon concentration and therefore determine the best areas to conduct future surveys. Geographic Information System (GIS) mapping software was used to construct maps of South Dakota that included levels of uranium concentrations in soil and stream wa...

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 ...
