Radon Testing in Schools

To continue providing safe, healthy school facilities where students learn, grow and play, Eugene School District 4J is testing all schools for radon.

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 is testing for radon in advance of state requirements; a new state law requires 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.

The Eugene School District 4J Radon Plan is available here: 4J Radon Plan

The district has engaged an independent professional environmental service to conduct the radon testing. Testing began in November 2018 and will be completed at all district schools in the following months.

The test is non-invasive and poses no danger to staff or students. It consists of placing an air-sample collection packet for several days in rooms that are in contact with the ground.

Please do not tamper with or move the test kits, and keep exterior windows and doors closed (except for normal entry/exit) during the testing period.

Radon test results will be posted on this website as they become available.
