A nationwide survey carried out by the National Radiological Protection Bureau, a government body, showed that most homes in England, Scotland, Wales and Northern Ireland had an average level of approximately 20 becquerels per cubic metre (Bq m3). This is fairly low as the current ‘Action Level’ – the point at which the Health Protection Agency advises homeowners take steps to reduce indoor concentrations of radon – is 200 Bq m3.

Note that higher levels of radon are found in certain places around the UK.
