Measurement of radon in Work Places and Premises with radon detectors from the world’s leading laboratory

Radon is a radioactive gas, we can’t see, smell or taste it: you need special equipment to detect it. It comes from the rocks and soil found everywhere in the UK. The radon level in the air we breathe outside is very low but can be higher inside buildings. Employers are required, as far as reasonably practicable, to ensure the health and safety of employees and other people who have access to their work environment. This includes a suitable and sufficient risk assessment, and taking appropriate action where necessary. Work environments vary greatly in size and nature, but excessive radon levels can occur in almost any type of workplace. Employers are required by law to assess any risks to their staff while at work.

Employers must comply with the UK Health and Safety at Work Act 1974 and the UK Management of Health and Safety at Work Regulations 1999. This legislation requires employers as far as reasonably practicable to ensure the health and safety of employees and other people who have access to their work environment, for instance, members of the public in shops and schools.

Radon should be identified as a hazard if you have a workplace with one or more of the following circumstances:

  • Your building is in a radon Affected Area
  • Your building has a basement area that is occupied for more than 50 hours each year
  • You operate a mine, cave, or are responsible for any underground environments
  • Your business involves a suspected radon source such as ground water (e.g. water treatment works) or stored geological samples.

Should your workplace come into any of the above categories it should be tested.

Regulations apply if the radon level exceeds 300 Bq/m³ in any area. The combination of the radon level, occupancy time and workplace type will determine what action is required. The regulations that apply where 300 Bq/m³ is being exceeded are the UK Ionising Radiations Regulations 2017. The legislation requires employers to act if radon levels exceed the workplace threshold. Your radon measurement report will indicate whether you are above the 300 Bq/m³ threshold and need advice from our experienced Radiation Protection Adviser (RPA) as to remedial steps to be taken to reduce the radon level.

Where radon levels are satisfactory and below the 300 Bq/m³ threshold, the employer should simply keep a record of the results and review them by retesting after around ten years or if there are significant changes to the workplace structure or use.
