The greatest health risk from radiation in Ireland is caused by radon. It accounts for 56 per cent of the total radiation dose received by the Irish population. Up to 250 cases of lung cancer in Ireland every year can be linked to radon.
The EPA provides a radon measurement service which is accredited by the Irish National Accreditation Board to ISO 17025 for homes and workplaces.
Radon is a radioactive gas which is naturally produced in the ground from the uranium present in small quantities in all rocks and soils
You cannot smell, see or taste radon
Radon can only be measured with special detectors.
The EPA process of measuring radon in the home involves a series of simple steps
Our report will include the following information:
Measurements are recorded in becquerels per cubic metre (Bq/m3). The average indoor radon level in a home in Ireland is 89 Bq/m3 though levels of up to 500 times higher than this figure have been recorded.
Radon measurements are legally required in occupied ground-floor and basement areas of indoor workplace premises located in High Radon Areas.
However, it is possible to find workplaces with high radon concentrations in locations not designated as High Radon Areas. Therefore, we urge all employers to adopt a proactive approach to radon in the workplace and carry out a measurement regardless of location.
Only those workplaces or work areas with an occupancy of above 100 hours per year need be measured.
For an explanation of how workplace measurements should be carried out, see the booklet Planning Radon Surveys in Workplaces – Guidance Notes.
The process of measuring radon in the workplace involves a series of simple steps:
If the radon concentration in each measured area is below the statutory value of 400 becquerels per cubic metre (Bq/m3) no further action is required. The report should be kept on file.
If radon concentration is above the statutory value of 400 Bq/m3 in any area measured, you must notify the EPA Office of Radiological Protection using this form (note: this only applies if measurements are carried out by a private radon measurement service).
For more information on the actions an employer may take if high radon concentrations are found in aboveground workplaces read our guidance note.
