Since radon gas is colorless and has no smell, it is hard to detect. Testing for the gas will help determine mitigation approaches. You can use DIY kits in that market for testing. Such kits are available online or at the nearest hardware store. Alternatively, you can get the services of a professional tester, although it’ll take a few days to receive the results. You can buy a radon detector like alpha-track, indicating when the toxic gas is in the house. If you find elevated gas levels, you can install a ventilation system.
