“…The potential for high indoor radon concentrations depends on multiple factors including the amount of radium-226 in the ground underneath buildings, and the permeability of the ground. As a result, indoor radon tends to be correlated with local geology Barnet et al, 2008;Kemski et al, 2009;Scheib et al, 2009). The probability of homes in Northern Ireland having radon concentrations above the UK Action Level (AL, 200 becquerels per cubic metre of air, Bq m -3 ) is currently estimated on the basis of the results of radon measurements in homes, grouped by 1-km squares where there are sufficient results in the square, or interpolated from the nearest measurements for squares where there are too few results ).…”

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 radon measurements and geology that was originally developed for mapping radon potential in England and Wales. A refinement of this method was also investigated using linear regression analysis of a selection of relevant airborne and soil geochemical parameters from the Tellus project.

The radon potential map generated from the Tellus data agrees in many respects with the map based on indoor radon data and geology but there are several areas where radon potential predicted from the airborne radiometric and permeability data is substantially lower. This under-prediction could be caused by the radon concentration being lower in the top 30 cm of the soil than at greater depth, because of the loss of radon from the surface rocks and soils to air.

“…High radon is also associated with Paleozoic metamorphic and volcanic rocks and also with uranium mineralization in the Pribram area (Barnet et al, 2008;Barnet et al, 2010) In Germany the highest radon occurs over the granites and Paleozoic basement rocks. Median soil gas radon for some granites ranges from 100 to 200BqL -1 ) (Kemski et al, 2009). In contrast, the highest radon potential in Belgium is associated with strongly folded and fractured Cambrian to Lower Devonian bedrocks in which uranium preferentially concentrated in ferric oxyhydroxides in fractures and joints is considered to be the main source of radon .…”

“…In order to derive predictive models relating geological information with indoor radon potential, uranium/radium concentrations in rocks and soils, terrestrial gamma radiation surveys, and soil gas radon measurements have been studied extensively in various locations at small geographic scales where good statistics on indoor radon measurements were available (Dehandschutter 2006;Doyle 1989;Doyle et al 1990;Kemski et al 1992Kemski et al , 2002Kemski et al , 2008. Those predictive tools have been successfully implemented to produce radon potential maps, such as in Sweden at a municipal level and in Spain and Estonia on national scales.…”

A preliminary design of a radon potential map for Canada: a multi-tier approach

Canada is a vast country with most of the population living on a small portion of the land. However, for a national radon potential map, it is mandatory to cover the entire country including sparsely populated areas. Because of these characteristics, the radon map development for Canada is challenging. After briefly reviewing of radon map development in the world, this study considers a multi-tier approach to best use available however limited resources and to generate a national radon map in a timely fashion. In summary, radon potential maps for highly populated areas should be determined by direct indoor radon measurements where enough indoor radon data are available. In areas where indoor radon measurements are limited or not yet available, the radon potential maps could be developed from various data sources with a multi-factor scoring system including geological information on soil permeability, soil gas radon concentration and ground uranium concentration. In sparsely populated areas, radon potential maps can only be generated with geological predictive tools, especially in those areas where no houses have yet been built. Because indoor radon measurement data and geological information relevant to radon are very limited in Canada, a multi-step strategy is also worth considering in addition to the multi-tier approach.
