A continuous radon monitor is a device that measures radon gas levels in your home over time, alerting you to dangerous fluctuations. Unlike single-use test kits, these keep tracking, which is crucial because radon, a radioactive gas from soil, can cause lung cancer. I use one in my basement, and it's easy to set up—just plug it in and watch readings on a screen or app. It's a practical tool for any homeowner worried about long-term exposure.
