Purpose

The CLOVER study seeks to understand exposure to radon in North Carolina homes, Radon is the second leading risk factor for lung cancer in North Carolina. The study project seeks to establish any links with climate change and exposure to radon. Our goal is to quantify the burden of radon-induced lung cancer in North Carolina and place emphasis on reaching members of vulnerable populations. Results will directly inform state policies and funding to improve radon awareness, testing, and mitigation and lower the burden of lung cancer in North Carolina.

What is Climate Change?

Climate change refers to long-term shifts in temperatures and weather patterns.

Climate change can affect us all in several ways.

What is Radon?

Radon is a colorless, odorless, tasteless, and naturally-occurring radioactive gas that can cause lung cancer.

Radon is found in rocks and soil. When radon escapes from the soil or is burned in fossil fuels (coal, oil, etc.) it spreads into the air around us and our homes. Radon can also be found in water.

​

To test for radon in your home, you can order a radon test kit which will tell you the concentration of radon in picoCuries per liter of air (pCi/L). High levels of radon include results from 4 pCi/L or more.
