Radon awareness in Ireland is slipping at a time when the health risk remains serious, according to the Environmental Protection Agency (EPA). The latest warning highlights a growing gap between public recognition of the radioactive gas and the need for practical action in homes, workplaces and public buildings across the country.
Radon is a naturally occurring radioactive gas that cannot be seen, smelled or tasted. It enters buildings from the ground and can build up indoors, especially in poorly ventilated spaces. The EPA says long-term exposure is a major concern because radon is the second leading cause of lung cancer after smoking, making this a public health issue that stretches across Health, Housing, Local Government and Heritage, and wider public policy on gov.ie.
Radon awareness in Ireland is trending in the wrong direction
The EPA’s message is clear: fewer people appear to understand what radon is, how it affects health, and why testing matters. That decline in awareness raises concern for households, landlords, employers and public bodies that rely on accurate health information from agencies such as the Health Service Executive (HSE), the Citizens Information Board and local authorities.
For policymakers and public service organisations, the warning also has implications for workplace safety, building standards and awareness campaigns. Bodies linked to Health, Social Protection, Education and Workplace Relations Commission (WRC) guidance may all play a role in ensuring the public gets clear information on exposure risks.
- Radon is invisible and odourless
- It can accumulate in any building, including homes and offices
- Smoking combined with radon exposure sharply increases lung cancer risk
- Testing is the only way to know if levels are too high

Why testing and remediation matter
The EPA has long advised people in affected areas to test their properties and take corrective action where necessary. A radon test is simple, relatively low-cost and remains the only reliable way to measure indoor levels. If elevated readings are found, remediation can include improving ventilation, sealing entry routes or installing a radon sump.
This matters not only for private homeowners but also for employers, schools and public sector estates managed across different departments, including Public Expenditure, Education and the Office of Public Works (OPW). In regulated environments, attention to indoor air quality also intersects with broader oversight from agencies such as HIQA and the Environmental Protection Agency (EPA).
Who should pay attention now
- Homeowners in known high-radon areas
- Landlords and housing providers
- Employers responsible for indoor workplaces
- Schools, community buildings and public offices
- Families with smokers, where the health risk is significantly greater

What the EPA warning means for the public
The EPA’s update is less about alarm and more about urgency. Radon awareness must improve so people understand the link between exposure and lung cancer, especially as Ireland continues to focus on prevention, public information and safer buildings. Stronger communication across gov.ie, the Health Service Executive (HSE), local councils and the wider public sector could help reverse the decline.
For anyone unsure about their property, the takeaway is straightforward: learn the risk, arrange a test, and act if levels are high. As the EPA stresses, radon awareness is not just about information; it is about protecting health through early detection and practical mitigation.
