Radon in Schools

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.

Radon testing in schools is not mandatory in California and there is no state funding specifically set aside to help school districts pay for testing. However, some schools have been able to voluntarily test their classrooms. 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.

Administrative Tools

The EPA has included radon in its free Indoor Air Quality for Schools Action Kit. Radon should be considered as part of a comprehensive indoor air quality plan for schools. More information on radon and the EPA Action Kit can be viewed here:
