When it comes to your child’s safety, most concerns focus on what you can see, like security, cleanliness, and building conditions. But one of the most serious risks is completely invisible. Radon gas can exist in schools without any warning signs, making it a hidden concern for parents and educators alike.
Radon is a naturally occurring radioactive gas that forms when uranium breaks down in soil, rock, and water. It can enter buildings through cracks in foundations, gaps around pipes, and other small openings. Because it is colorless and odorless, the only way to detect radon is through proper testing.
While many people associate radon with residential homes, schools are just as vulnerable. In fact, recent findings highlight just how widespread the issue can be. A 2026 report found that nearly a quarter of schools tested had at least one room with radon levels above the EPA’s recommended action level. This means that in many cases, students and staff could be spending hours each day in spaces with elevated radon levels without even knowing it.
On a broader scale, the Environmental Protection Agency estimates that nearly one in five schools nationwide has at least one classroom with high radon levels, impacting tens of thousands of classrooms. These statistics reinforce an important reality: radon in schools is not rare, and it should not be overlooked.
Children may be particularly at risk because of the amount of time they spend in school buildings. Long term exposure to elevated radon levels increases the risk of lung cancer, making it one of the leading environmental health concerns in indoor air quality. The challenge is that without testing, there is no way to know whether a school has a problem.
School buildings themselves can contribute to the issue. Large footprints, multiple foundation types, aging infrastructure, and varying ventilation systems can all create pathways for radon to enter and accumulate. Lower level classrooms, basements, and areas with limited airflow are often the most susceptible.
The good news is that radon is both detectable and fixable. Testing is simple and cost effective, and mitigation systems can significantly reduce radon levels when needed. Addressing radon is not about creating fear, but about taking proactive steps to ensure safe environments for students and staff.
Parents can play an important role by asking school administrators whether testing has been completed and how often it is conducted. Awareness is the first step toward action, and in many cases, it can lead to meaningful improvements in indoor air quality.
