Some basic questions about radon

What is radon?
Radon (chemical symbol Rn) 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 the gas, mostly in 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 building’s occupants. The main danger from high radon exposure is the increased risk of lung cancer.
What is the safe limit for radon?
The unit of measurement of radiation is the Becquerel. 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 states that employers must keep workplace radon levels below 300 Bqm-3 (annual average) to comply with UK law.

Radonorm SLO project, Slovenia
UK Radon Ltd has been proud to partner in Radonorm SLO, a project focusing on creating greater awareness of radon in communities across the country, by using citizen science to measure and remediate radon.
Participants first measured radon levels in their homes and learned about its effects and the various means of remediating radon. Some example homes with radon concentrations above the 300 bqm-3 Slovenian radon action level were then remediated by local contractors directed and advised by UK Radon Ltd. These homes were then remeasured to show the dramatic reductions in radon concentrations achieved through remediation.
