As more than 55 million children and 6 million adults spend their days in K–12 school buildings nationwide, the American Lung Association is calling on school administrators to prioritize indoor air quality by testing for radon—a leading cause of lung cancer that poses a hidden threat in many educational institutions.
Radon is a naturally occurring, odorless, tasteless, and colorless radioactive gas that can accumulate indoors. It is the second leading cause of lung cancer in the United States, responsible for around 21,000 deaths each year. Testing is the only way to determine if a school has elevated levels of this hazardous gas.
“Every child deserves a healthy place to learn, and every educator deserves a healthy place to work,” stated Harold Wimmer, President and CEO of the American Lung Association. He emphasized that “radon is a cancer-causing gas that can accumulate inside schools without anyone knowing.” He reiterated that testing for radon is simple and affordable, and schools can take action to mitigate the problem if high levels are detected.
Indoor air quality is crucial for both student learning and staff health. With Americans spending about 90% of their time indoors, where air pollution levels can be two to five times higher than outdoor levels, poor air quality in schools has been linked to reduced academic performance, increased absenteeism, and a higher risk of respiratory illnesses along with other serious health issues.
Radon often enters buildings through cracks in floors, walls, and foundations, making it essential for schools to take proactive measures. The Environmental Protection Agency (EPA) advises that action should be taken to reduce radon if levels are at or above 4.0 picocuries per liter (pCi/L) and suggests considering action for levels between 2.0 and 4.0 pCi/L. In many states, school officials can be trained to conduct radon testing, or licensed professionals can be hired to carry out the tests. Comprehensive guidance for radon testing in schools is readily available.
The American Lung Association’s campaign encourages schools to prioritize not just education, but the health and safety of students and staff alike—starting with the air they breathe.
