Radon Leading Cause of Lung Cancer

Radon is the leading cause of lung cancer among non-smokers. When radon decays, the particles released are strong enough to pit plastic. More than 20,000 Americans die every year from radon.

Protect Yourself & Your Family

Simple steps can protect you and your family. Homes with high levels of radon can be fixed, and new homes can be built with radon-resistant new construction (RRNC) features.

Radon Mitigation System Inspections Findings 2002-2011

Since 2002, Boulder County Public Health staff has inspected 91 residential radon mitigation systems throughout Bouder County as part of the Indoor Radon Grant.  The objective of the inspections is to ensure that systems were properly installed, to encourage owners to actively keep their systems in good repair, and to encourage system owners to test their systems every two years to ensure that their system is still protecting their families from radon. Short-term radon tests were performed in conjunction with every system inspection.

A comprehensive list of the systems inspected, the associated radon levels, and the recommendations are included the Radon Mitigation System Inspections Findings report.
