This list of registered radon testing services is published by the Environmental Protection Agency to provide information to members of the public and employers. The EPA does not warrant the services being provided by any registered service. Listed services have met the relevant criteria required to become a registered radon testing service.
More details about the requirements of this scheme are available in the Registration Form and Guidelines and all listed services must comply with the EPA's Measurement Protocol.
Please contact the testing services directly for a quote for testing your workplace as the costs vary depending on the number of radon detectors required.
To test your home, you will need to buy a radon testing kit directly from one of the testing companies above. This costs about €50.
Radon detectors are small, round, plastic discs about the size of the palm of your hand. You place one in the living room and one in the main bedroom (the rooms in the home where you and your family spend most of your time) and leave them for three months. Radon detectors are passive detectors, this means that they collect radon automatically, so they simply need to be placed in your home.
After three-months, you send the detectors back to the testing service for analysis and you’ll then receive a report with your results.
Every home has different amounts of radon so even if your neighbours have tested their home for radon, you should still test your home.

If your radon results are above 200 Bq/m3, you will need to carry out remediation work to reduce your levels. Once you have completed any remediation work, you should retest to ensure your levels have reduced to below 200 Bq/m3. This is called a post-remediation test. Please contact us for more information on this free post–remediation test.
If your results were above 200 Bq/m3 and you have carried out remediation work, you should retest every 5 years to check that your radon levels remain low and ensure the remedial work remains effective.
If your radon results are below 200 Bq/m3 no further action is required unless you carry out major refurbishment work to your home. For example:
If you test your home and discover radon levels above 200Bq/m3, and have carried out remedial works to reduce your levels, you can avail of a free post-remediation test through the EPA to ensure the remedial works have reduced your levels.

By law (Statutory Instrument No.30 2019 (PDF)) employers located in High Radon Areas are required to test their premises for radon. The acceptable level, or Reference Level, for workplaces in Ireland is 300 becquerels per cubic metre (Bq/m3).
Workplaces must be tested for radon according to the guidelines set out in the EPA Measurement Protocol. To purchase detectors, please contact the EPA Registered Radon Testing Services listed at the top of this page. The cost will vary depending on the number of detectors required.
Radon testing must be carried out for at least three months. A report with the radon level in each room tested will then be sent to you.
For underground workplaces such as caves and mines, please contact us for advice.
If your workplace has radon levels above the national workplace Reference Level (300Bq/m3):
If your workplace cannot be reduced to below the reference level following remediation work, please contact us for further advice.
If your radon results are below 300 Bq/m3 no further action is required unless you carry out major refurbishment work to the building. For example:
The national Reference Level for radon in workplaces (300 Bq/m3) applies to schools also. However, the Department of Education set an advisory Reference Level of 200 Bq/m3 for schools in 1998. This is the same as the Reference Level for radon in homes. These two Reference Levels are applied as follows:
A radon test is carried out by placing a small detector in every occupied ground floor classroom and office for three months. Only rooms that are occupied for more than about 100 hours per year need be measured so you do not need to test corridors, bathrooms or storage areas.
Please contact the Devolved Projects Section of the Department of Education who will fund testing and any remediation work required.
When your radon test is complete, and your radon detectors have been analysed, a copy of the results will be sent to your school.
