Radon detection and remediation

UK Radon Ltd's website is one of the UK's most comprehensive resources for all matters relating to radon in both domestic and commercial buildings.

What is radon?

Radon is a naturally-occurring colourless, odourless radioactive gas that is formed from the radioactive decay of uranium as it naturally occurs. It is associated with many types of geology including granite and limestone, and can be found all over the British Isles.

All homes contain radon, most having low concentrations. However if radon occurs in higher concentrations in enclosed spaces, such as buildings, it can, potentially, have serious impacts on the health of the buildings occupants. The main danger from high radon exposure is the increased risk of lung cancer.

How much is too much?

Public Health England (PHE) recommends that radon levels in homes should be below the 200 Becquerels per cubic metre (Bqm-3) (annual average) 'Action' level, and preferably below the 'Target' level of 100 Bqm-3 for smokers and ex-smokers.
The Health and Safety Executive, state that employers must keep workplace radon levels below 300 Bqm-3 (annual average) to comply with UK law.
