Radon Aware Colorado

Colorado Residents Are at Risk

Public health agencies across Colorado have come together to create the Public Health Radon Aware Colorado initiative to reduce exposure to radioactive radon gas and the associated risk of lung cancer.

In Colorado, 50% of homes have unhealthy radon levels; that’s equivalent to every person in the residence having 200 chest x-rays every year. This compare with only 6% of homes having unhealthy radon levels across the rest of the country.

Radon is the leading cause of lung cancer deaths among nonsmokers in the U.S. and claims the lives of about 21,000 Americans each year. This is more people than breast, prostate, colon, and liver cancers combined! Radon exposure causes as many as 500 lung cancer deaths every year in Colorado.

Action Steps

It takes actions by all of us to reduce radon risk and save lives. Below are actions real estate and building industry professionals, homebuyers, rental property owners, policy-makers, and local public health agencies can take to protect children, families, and their communities:

  • Builders & Building Professionals : Use the latest Colorado technical guidance to build radon resistant new homes and watch how to install radon-resistant construction techniques (RRNC) in new single- and multi-family homes.
  • Building Departments: Learn about radon-resistant new construction and radon mitigation in this technical guidance for Colorado and inspection procedures for ensuring radon systems are installed correctly in new homes.
  • Homebuyers: Test for radon. Fixing the problem is easy and inexpensive.
  • Rental Property Owners: Test your rental for radon. Inform renters, in writing, before a lease is signed that the rental space has been tested for radon and disclose the results.
