Radon Testing in Schools

To continue providing safe, healthy school facilities where students learn, grow and play, Eugene School District 4J completed testing of all schools for radon in the 2018-19 school year.

Radon is a naturally occurring gas that comes from the breakdown of uranium in soil and rock. Breathing high levels of radon over a long period of time can cause lung cancer. Radon can work its way into buildings, including homes and schools, through cracks in the ground and openings in foundations or under structures. You can’t see, smell, or taste radon. The only way to know if a building has elevated radon is to use specialized testing equipment.

The district completed testing for radon in advance of state requirements; a state law required that all districts in Oregon test school buildings for radon before January 1, 2021. The goal of the Oregon Healthy & Safe Schools Plan is to ensure radon levels are under 4.0 picocuries per liter of air (pCi/L), a limit set by the EPA. Testing for Radon is required every 10 years.
