Radon in Schools

Radon Could Be a Serious Threat to Your School

Every School Should Take This Simple Test

Chances are you've already heard of radon - a radioactive gas that can cause lung cancer.

But what you might not have heard is that high levels have been found in a number of schools across the country. Therefore, it is important that students, teachers and parents be aware that a potential problem could exist in their school.

A nationwide survey of radon levels in schools estimates that nearly one in five has at least one schoolroom with a short-term radon level above the action level of 4 pCi/L (picoCuries per liter) - the level at which EPA recommends that schools take action to reduce the level. EPA estimates that more than 70,000 schoolrooms in use today have high short-term radon levels.

The only way to determine if a problem exists is to test for it. Having your school tested for radon is something you may want to discuss with your school officials. Because as real as the threat of radon is, the good news is that the problem can be solved.

EPA's national survey of schools produced some alarming results about concentrations in our children's classrooms. Public awareness must be raised about the hazards of radon to hasten efforts to reduce the danger. All schools must be tested to determine if there is a problem, and schools must inform parents of the results. We cannot ignore this problem."Kathryn Whitfill, National PTA President.

Radon could be a serious threat in your school

The EPA ranks indoor radon among the most serious environmental health problems facing us today. After smoking, it is the second leading cause of lung cancer in the United States causing an estimated twenty one thousand (21,000) lung cancer deaths a year.

Radon is a naturally occurring gas that seeps into buildings from the surrounding soil. In some cases, well water may be a source of radon.

You can't see, taste, or smell radon. In fact, the only way to discover if high levels of radon are present is through testing.

All students have the right to expect a safe and healthy environment. Teachers and other school employees should encourage their schools to conduct radon tests and undertake all necessary corrective actions. The health of our children demands no less.Keith Geiger, NEA President.

Radon gas decays into radioactive particles that can get trapped in your lungs when you breathe.

As these particles break down, they release small bursts of energy. This can damage lung tissue and lead to lung cancer over the course of your lifetime. An individual's risk of getting lung cancer from radon depends mostly on three factors: the level of radon, the duration of exposure and their smoking habits.

EPA recommends that all schools nationwide be tested for radon. To date, approximately 20% of the schools nationwide have done some testing. Some states have tested all their public schools.

How are schools tested for radon?

Testing for radon is simple and relatively inexpensive. EPA has published guidance that is available free to schools throughout the country.

The basic elements of testing are:

  • Test all frequently used rooms on and below the ground level;
  • Conduct tests in the cooler months of the year; and,
  • Follow the testing strategy below.

Testing and Mitigation Standards for Schools

Copies of the following Radon Standards of Practice may be viewed, purchased or printed from Association of Radon Scientist and Technologists Standards webpage Exit, or from the American National Standards Institute store Exit.

Radon Mitigation Standards for Schools and Large Buildings (RMS-LB 2014)

Radon Mitigation Standards for Schools and Large Buildings (RMS-LB 2014)
This new American National Standard addresses the complexities of properly mitigating radon in large and complicated building structures that require specialized techniques and quality assurance to address complicated building designs and specialized airflow.

Protocols for Measuring Radon and Radon Decay Products in School and Large Buildings (MALB 2014)

Protocols for Measuring Radon and Radon Decay Products in School and Large Buildings (MALB 2014)
This new American National Standard addresses the complexities of properly measuring radon in large and complicated building structures that require specialize techniques and quality control and assurance to address complicated building designs and specialized airflow.

What happens if your school fails the test?


Every home should also take this test. Fortunately, even if your school does fail the radon test, the problem can be corrected. Proven techniques are available that will lower radon levels and lower risks of lung cancer from radon exposure.

School is not the only place that students and teachers can be exposed to radon.

Since children spend more time at home, high radon levels there can pose a much greater threat to their health.

Once again, testing is simple and inexpensive. After all, radon is one health problem nobody should have to live with - at home or at school.

For more information, call one of the radon hotlines or contact your state radon coordinator.

The American Lung Association
Recommends testing homes and schools for radon.

U.S. Surgeon General Health Advisory
"Indoor radon gas is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the country. It's important to know that this threat is completely preventable. Radon can be detected with a simple test and fixed through well-established venting techniques." January 2005
