The Kidde Radon Detector Kit allows you to quickly and accurately test for radon gas in your home or workplace. Radon is an odorless, tasteless, invisible and radioactive gas, a natural by-product of decaying uranium. In outdoor air, radon is diluted to such low concentrations that it is usually nothing to worry about. However, once inside an enclosed space such as a home, radon can accumulate. Along with your specific test results, you will receive information on how to conduct follow up tests, as well as a detailed list of governmental agencies to contact for more information.
