Radon is an invisible, odorless gas created by the natural radioactive breakdown of uranium in soil, rock and water. It enters buildings through cracks in floors or walls, construction joints and gaps in suspended floors. It can also enter via service pipes and cavities inside walls. Two houses side-by-side can have different radon levels due to the geology below the homes. According to the EPA, radon is the leading cause of lung cancer among non-smokers. It is estimated to cause about 21,000 lung cancer deaths per year. For additional information please read Boulder County’s Brochure: Is Your Home Safe From Radon?
The City of Longmont's Public Works & Natural Resources Department has made several Safety Siren™ Radon Gas Detectors available to library patrons so that they can easily test the levels of radon gas in their homes. Check a meter out from the Library (350 Kimbark Street).Recommendation: If short-term radon test results are over 10pCi/L, confirm with a National Environmental Health Association (NEHA) or National Radon Safety Board (NRSB) approved short-term device. If the results are less than 10 pCi/L, conduct an approved long-term radon test. To learn how to use the Radon detectors please read the brochure: Information for Use of Safe SirenTM Radon Detectors
