Radon (222Rn) is a natural radioactive gas that occurs in rocks and soils and can only be detected with special equipment. Radon is a major cause of lung cancer. Therefore, early detection is essential. The British Geological Survey and Public Health

Gamma radiation from naturally occurring sources (including directly ionizing cosmic-rays) is a major component of background radiation. An understanding of the magnitude and variation of doses from these sources is important, and the ability to pred

Studies of underground miners occupationally exposed to radon have consistently demonstrated an increased risk of lung cancer in both smokers and non-smokers. Radon exposure also occurs elsewhere, especially in houses, and estimates based on the find

In this paper, a simple model for analysing variability in radon concentrations in homes is tested. The approach used here involves two error components, representing additive and multiplicative errors, together with variation between-houses. We use

ANOVA is used to show that approximately 25% of the total variation of indoor radon concentrations in England and Wales can be explained by the mapped bedrock and superficial geology. The proportion of the total variation explained by geology is high

Etched-track passive radon detectors are a well established and apparently simple technology. As with any measurement system, there are multiple sources of uncertainty and potential for error. The authors discuss these as well as good quality assuran

Data collected as a part of a survey on radon concentrations from about 40 000 dwellings in England for six contrasting geological units were analysed to evaluate the impact of house-specific factors (building characteristics and construction dates)

The HPA operates a radon measuring service determining the radon concentration ( Bq m - 3 ) in enclosed areas using passive PADC (CR-39) detectors. Since 2003 over 116,000 radon detectors have been analysed in the laboratory using a Nikon LS2000 slid

In order to provide an area-monitoring passive radon detector that is resistant to very high humidities, passive detectors have been heat-sealed in 200 microm thick polyethylene. The sensitivity of the detectors in the bags to radon was found to be 8

The area of etched tracks in CR-39 (polyallyl diglycol carbonate, PADC) exposed to alpha-particles from an americium-241 source has been investigated as a function of post-exposure storage time in a dry nitrogen atmosphere. Data were collected over 2
