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 22–26 is Radon Awareness Week. This year’s theme is “What’s Your Radon Story?” Each day of the week features facts about radon with related graphics, social media messages, and highlighted radon story:

• Monday: Who is affected by radon?
• Tuesday:  What are the health effects of radon?
• Wednesday: Where are people exposed to radon?
• Thursday: When should I install a radon reduction system?
