Radon awareness in Ireland is slipping at a time when the health risk remains serious. The Environmental Protection Agency (EPA) has warned that public understanding of radon, how it enters homes and workplaces, and its link to lung cancer is declining, underscoring the need for renewed action across households, employers and public bodies.
As one of the leading environmental and public health issues on gov.ie and across Irish public information campaigns, radon awareness matters because radon is a radioactive gas you cannot see, smell or taste. Yet long-term exposure can damage health, especially in poorly ventilated buildings and in areas known to have higher radon potential.
Radon awareness in Ireland is declining, says the EPA
The EPA’s latest warning points to a worrying trend: fewer people appear to understand the dangers of radon or the steps needed to reduce exposure. That matters because radon remains the second biggest cause of lung cancer after smoking, making radon awareness a significant public health priority for Ireland.
The issue also cuts across multiple parts of the public sector, including Health, Housing, Local Government and Heritage, and Education. Agencies such as the Health Service Executive (HSE), Citizens Information Board and local authorities all have a role in helping people access guidance, testing information and remediation supports where available.
- Radon is a naturally occurring radioactive gas.
- It can build up indoors in homes, schools and workplaces.
- There are no immediate symptoms from exposure.
- The main long-term risk is lung cancer.
Why the warning matters now
Public health campaigns rely on awareness translating into action. If fewer homeowners, tenants, schools or employers test their buildings, more people may continue to live or work with elevated radon levels without knowing it. That is why the EPA’s message is important not only for the public, but also for bodies such as the Workplace Relations Commission (WRC), the Office of Public Works (OPW), Tusla and the National Shared Services Office when managing buildings and staff safety obligations.

What people should know about radon awareness
Improving radon awareness starts with the basics. Radon comes from the ground and can seep into buildings through cracks, gaps around pipes and other openings. Some areas of Ireland have a greater risk, but any building can potentially be affected. Testing is the only reliable way to know whether a property has a radon problem.
For households and businesses, the key steps are straightforward:
- Check whether your area is considered at higher risk.
- Arrange a radon test for your home or workplace.
- If levels are high, seek advice on remediation measures.
- Retest after works are completed.
This public information effort aligns with wider state priorities involving the Revenue Commissioners, Department of the Taoiseach, Social Protection and Enterprise, Trade and Employment, especially where workplace safety, housing standards and citizen outreach overlap.
How Irish agencies support public information
While the EPA leads on environmental guidance, broader awareness often depends on cooperation across agencies. The HSE can reinforce the health message, local councils can support housing communication, and data-led bodies such as the CSO may help shape future public understanding. In the same way that the Road Safety Authority (RSA) and Food Safety Authority (FSAI) use public campaigns to change behaviour, radon awareness needs regular, easy-to-understand communication.

What happens next for radon awareness in Ireland?
The EPA’s warning is ultimately a call for renewed engagement. Better messaging on gov.ie, clearer building guidance, stronger workplace communication and more frequent local campaigns could all help reverse the decline in radon awareness. For the public, the takeaway is simple: radon is invisible, but the risk is real, and testing remains the most important step.
As Ireland continues to focus on prevention in Health, Climate Action and housing policy, radon awareness should remain part of the national conversation. A small test today could make a major difference to long-term health outcomes tomorrow.
