Radon is an odorless and invisible radioactive gas naturally released from rocks, soil, and water. In outdoor environments, radon levels are very low and generally not considered harmful. However, radon can get into homes or buildings through small cracks or holes and build up to higher levels. Over time, breathing in high radon levels can cause lung cancer.

January 23–27 is Radon Awareness Week. This year’s theme is “The 5Ws of Radon: What’s Your Radon Story?” Each day of the week features one of the 5Ws with a related graphic, social media, and highlighted radon story:

• Monday: Who does radon affect?
• Tuesday: What are the health effects of radon?
• Wednesday: Where can I be exposed to radon?
• Thursday: When should I install a radon reduction system?
• Friday: Why should I raise awareness about radon?
