Radon gas is a naturally occurring radioactive gas that can come up from the ground directly into your home. It is odorless and tasteless, so without a radon detector, you may not realize how high the levels in your residence actually are. This portable detector lets you check levels anywhere in your home with the average daily, weekly, and long-term concentrations displayed. Plus, it’s battery-powered so you don’t need an outlet nearby!
