Radon Testing

In our continued efforts to provide safe and healthy schools for our students and staff, the Medford School District is testing for radon in schools. A new state law requires that all districts in Oregon test schools for radon before January 1, 2021.

Radon is a naturally occurring gas that comes from deposits in the soil. It is colorless, odorless, and tasteless and can work its way into buildings through cracks in the ground and openings in foundations or under structures.

According to the Environmental Protection Agency (EPA), radon is the number one cause of lung cancer among people who do not smoke. The threat of elevated radon levels in Southern Oregon is considered low; however, testing is the only definitive way to determine actual radon levels.

Testing is non-invasive and poses no danger to staff or students. It consists of placing a small container (test kit) in all rooms that people typically occupy and leaving it there for several days. The kits are then sent to a lab for analysis and results are posted at: 

While people may be exposed to elevated radon levels in schools, EPA data shows exposure at home is the number one source of radon exposure for most people. The EPA and Oregon Health Authority (OHA) recommend that all homes be tested for radon.
