To use a radon testing kit, follow these general steps: 1. Place the kit in the lowest living area of your home, where radon levels are likely to be highest. 2. Ensure the area around the kit is undisturbed and that doors and windows remain closed as much as possible during the testing period. 3. After the testing period, seal the kit and send it to a laboratory for analysis. 4. The laboratory will provide a report on the radon levels detected.
