Winter‐to‐winter variations in indoor radon
Journal of Toxicology and Environmental Health, 1989Indoor radon concentrations in northern Virginia and central Maryland show a strong dependence on weather. Winter tends to be associated with higher than average indoor radon, and summer with lower than average. However, compared to the winter of 1986-1987, the winter of 1987-1988 was warmer and drier.

Physics World, 1988
Some 10,000 people are estimated to contract lung cancer each year in the USA from indoor exposure to the decay products of radon (radon-222); for the UK, the estimate is about 1500. Extensive surveys of population exposure to radon have been carried out in many countries, including the UK.

The path from geology to indoor radon
Environmental Geochemistry and Health, 2020It is generally accepted that radon emission is strongly influenced by the geological characteristics of the bedrock. However, transport in-soil and entry paths indoors are defined by other factors such as permeability, building and architectural features, ventilation, occupation patterns, etc.

Indoor radon concentrations in Adana, Turkey
Radiation Protection Dosimetry, 2008The indoor radon concentration in Adana, Turkey was measured in living rooms of 52 houses during winter 2005 and 57 houses during summer 2005. Forty-four houses were selected for both winter and summer researches for estimating seasonal variations. Indoor radon concentrations were measured seasonally over hotter and colder 2 months over the whole year,

Indoor Radon Maps of the United States
Health Physics, 1994A recently published compilation of average radon levels in 1,729 U.S. counties with standard errors of approximately 20% is used to generate maps exhibiting these results and showing correlations over multicounty areas. Several large areas and numerous smaller areas with high radon levels are identified.

Status of the European indoor radon map
Radiation Protection Dosimetry, 2011Since 2006 a European map of indoor radon (Rn) concentration is in the making. So far 20 countries have contributed with national data, allowing a fair coverage of parts of Europe. This paper presents the current (September 2010) state of the map, discusses its rationale, presents some statistical findings and addresses a few problems which arose ...

Indoor radon levels in Greek schools
Journal of Environmental Radioactivity, 2011Radon and gamma dose rate measurements were performed in 512 schools in 8 of the 13 regions of Greece. The distribution of radon concentration was well described by a lognormal distribution. Most (86%) of the radon concentrations were between 60 and 250 Bq m(-3) with a most probable value of 135 Bq m(-3). The arithmetic and geometric means of the radon

Comparisons Between Soil Radon and Indoor Radon
Energy Sources, 1999Several thousand indoor radon measurements have been obtained for homes in northern Virginia. Compilations of these data according to the geologic units under the homes show that some units have relatively high or relatively low median indoor radon levels, and that these differences persist through all four seasons.

Groundwater treatment as a source of indoor radon
Applied Radiation and Isotopes, 2014New Viimsi Parish water treatment plant (Northern Estonia) was investigated in order to determine whether the open filter columns serve as a source of (222)Rn generation in the treatment process and whether they influence indoor air (222)Rn activity concentrations.

Indoor Radon and Lung Cancer in China
JNCI: Journal of the National Cancer Institute, 1990Radon has long been known to contribute to risk of lung cancer, especially in undergound miners who are exposed to large amounts of the carcinogen. Recently, however, lower amounts of radon present in living areas have been suggested as an important cause of lung cancer.
