Approximately 200 volume traps were retrieved from dwellings in various radon prone areas in Europe. They were analysed for the purpose of retrospective radon assessment. Emphasis is put on specific problems encountered when using field samples as opposed to laboratory exposed samples. It was seen that in very dusty circumstances, direct penetration of radon decay products from the outside to t...

High radon concentrations indoors usually depend on the possibilities of radon penetration from the surrounding soil into the buildings. Radon concentrations in dwellings up to 100 kBq/m3 were found in some special regions (i.e. Schneeberg/Saxony, Umhausen/Tyrol), where the soil shows a high uranium content and additionally, a fast radon transport in the soil is possible. To reduce the radon ex...

Radon and radon progeny are present indoors, in houses and others dwellings, representing the most important contribution to dose from natural sources of radiation. Most studies have demonstrated an increased risk of lung cancer at high concentration of radon for both smokers and nonsmokers. The work presents a comparative analysis of the radon exposure data in the two radon-prone areas, Stei, ...

The aim is to compare lung cancer risks from radon in smoking categories in Czech residential radon and uranium miners studies and to evaluate interactions between smoking and radon exposure. The residential and occupational studies are based on one hospital based case-control study and three case-control studies nested within cohort studies, two among uranium miners and one in the general popu...

OBJECTIVE Radon is an important risk factor for lung cancer. Here we use maps of the geographic variation in radon to estimate the lung cancer risk associated with living in high radon areas of Canada. METHODS Geographic variation in radon was estimated using two mapping methods. The first used a Health Canada survey of 14,000 residential radon measurements aggregated to health regions, and t...

In order to reduce lung cancer due radon exposure situations, not only authorities and organisations but also citizens may meaningfully contribute mitigation actions. Citizen science (CS) initiatives are recognised for their scientific, societal policy value related environmental issues. The purpose of this paper is identify which CS in the field exist evaluate what extent these research and/or...

Radon is a naturally occurring radioactive gas that originates from the decay of uranium in rocks and soils and is linked to some 13% of lung cancer cases in Ireland. Between 1992 and 1999, the Radiological Protection Institute of Ireland (RPII)1 carried out a National Radon Survey (NRS) of Ireland to identify the areas of the country most at risk from high indoor radon levels. Those areas wher...

IEE Wiring Matters | Spring 2005 | www.iee.org Radon – a brief explanation Radon is a naturally occurring gas that has no colour, smell or taste. The gas comes from minute amounts of uranium present in all earth materials such as rocks, soil, bricks and concrete. Radon is present in all parts of the UK, but in the most populous areas the levels are quite low. Some of the highest levels are foun...
