ASSESS

Health and Safety at Work Act 1974
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. This includes a suitable and sufficient risk assessment, and taking appropriate action where necessary. Radon should be identified as a hazard if you have a workplace with one or more of the following circumstances:

  • it is a building in a radon Affected Area
  • it has a basement area that is occupied for more than about 50 hours each year
  • it is a mine, cave, or other underground environment
  • it has a suspected radon source such as ground water (e.g. treatment works) or geological samples.

MEASURE

If radon is an identified hazard, the workplace should be tested. Regulations apply if the radon level exceeds 400 Bq m-3 in any area. The combination of the radon level, occupancy time and workplace type will determine what action is required.

ACT

Ionising Radiations Regulations 1999

Ionising Radiations Regulations (Northern Ireland) 2000

Legislation requires employers to act if radon levels exceed the workplace threshold. Your PHE radon measurement report will provide straightforward advice on what to do next to manage and reduce high radon levels and to meet regulatory requirements. Our advice will include an offer of the services of our experienced Radiation Protection Advisers (RPAs).

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

Further advice is available from the HSE website.
