Radon - Summary

Radon is a naturally occurring odorless radioactive gas commonly found in association with granite based rock formations. Prolonged inhalation of elevated levels of radon gas may cause lung cancer in humans.

Due to the preponderance of granitic bedrock in Massachusetts, it was known that the evolution of radon gas was likely in Burlington. In addition, while surveying the local schools it was observed that each school was constructed with a sandy bottom crawl space rather than a sealed concrete slab or foundation. As a result, there existed the possibility that ledge may be present under the crawl space and that radon could enter the schools via the crawl space and adversely impact the indoor air quality.
