radon in a persons lungs

Radon is an odorless, radioactive gas that results from the natural decay  of uranium. Uranium is found in rock, soil, and water all over the world. Radon typically moves up through the ground to the air above and into your home through cracks and other holes in your home’s foundation.

Radon gas decays into radioactive particles that can get trapped in your lungs when you breathe. As they break down, these particles release small bursts of energy that can damage lung tissue and lead to lung cancer over the course of your lifetime.

Nearly 46% of all homes in Colorado are estimated to have elevated radon levels. The only way to know the radon level of your home is to test. It is inexpensive and takes only a few minutes of your time.

Short-term radon test kits are available at the health department, for FREE, while supplies.

Test kits may be picked up 8am-5pm, Monday-Friday, at either of these two locations:

  • 1555 N. 17th Ave., Greeley, CO 80631
