Modelling in-house radon potential using Tellus data and geology to supplement in-house radon measurements

摘要

It is well known that naturally occurring radon gas rising from the ground and accumulating in dwellings and workplaces is a cause of lung cancer, particularly among smokers. In the UK and Ireland, campaigns to measure and suppress radon in buildings have been proceeding for several years. This chapter considers how additional data from geological mapping and data from the Tellus surveys can improve our estimation of in-house radon potential. In the Republic of Ireland radon potential mapping has hitherto been based solely on indoor radon measurements, while in Northern Ireland indoor radon readings are supplemented with geological data. New radon modelling with Tellus airborne gamma-ray spectrometry and soil geochemistry, in combination with geological data and indoor radon measurements, has in some settings produced maps with more detailed spatial resolution. The process has identified some differences between the Tellus modelled maps and the current indoor radon maps. These should be validated with additional radon measurements, especially where the Tellus maps indicate higher radon potential and where in-house radon measurements are sparse. The Tellus-based radon maps should be used as an aid in future in-house radon measurement campaigns
