Radon management


"Radon is invisible; you can't see it, smell it or taste it, and its presence in your workplace can pose a danger to you and your employee's health. Breathing in radon is the second largest cause of lung cancer in the UK resulting in up to 2000 fatal cancers per year..."


What is Radon?

Radon is a naturally occurring radioactive gas that can seep out of the ground and build up in houses, schools, public buildings and indoor workplaces. The highest levels are usually found in underground spaces such as basements, caves and mines. High concentrations are also found in ground floor buildings because they are usually at slightly lower pressure than the surrounding atmosphere; this allows radon from the sub-soil underneath buildings to enter through cracks and gaps in the floor.


Legal Requirement

Employers are required by the Management of Health and Safety Regulations at Work 1999, to assess risks from radon in workplaces in Affected Areas, and this usually requires a measurement. The Ionizing Radiations Regulations 1999 require action to protect employees if the average radon gas concentration exceeds 400 Bq m-3 (becquerels per cubic metre of air).
