My radon alarm started chirping last week, and despite being a quiet little box on the basement wall, it got my full attention. It's easy to ignore the invisible gas, but that persistent beep reminded me radon is serious. I had to open windows and run a fan until levels dropped. Since then, I actually glance at it every morning—just to make sure.
