Indoor radon, geogenic radon surrogates and geology – Investigations on their correlation
Journal of Environmental Radioactivity, 2017The indoor radon concentration was measured in most houses in a couple of municipalities in Austria. At the same time the activity concentration of radium in soil, the soil gas radon concentration, the permeability of the ground and the ambient dose equivalent rate were also measured and the geological situations (geological units) were recorded too ...

The naturally radioactive but chemically inert gas, radon, is formed from the radioactive decay of radium which is part of the uranium series. Radon gas, which has a half life of 3.8 days, must escape from soil particles through air-filled pores in order to enter the atmosphere following the decay of radium. The concentration of radon in the atmosphere

Soil radon, permeability, and indoor radon prediction
Environmental Geology and Water Sciences, 1992Attempts to predict which geographic areas should be associated with a high percentage of homes with unusually high indoor radon levels have been based on estimates of soil radon and soil permeability for geological units. In northern Virginia and southern Maryland, it appears that predictions of indoor radon based on estimates of homesite soil radon ...

On the Behaviour of Radon Daughters in Indoor Air
Radiation Protection Dosimetry, 1984In the present work the effect of small aerosol particles and the effect of the air cleaning devices on the behaviour of the decay products have been studied. The long term measurements in a one-family house have shown that the behaviour of the decay products is strongly dependent on both the concentration of aerosol particles (i.e.

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 ...
