Radon testing services
Extinction Radon has some of the most advanced and reliable testing devices and methods in the industry. Within the last 15 years, many improvements and testing methods have been tried and developed in order to best determine indoor radon exposure. We use only the best processes and approved measurement devices that determine either the radon potential over a short period of time, or an average of the radon exposure over a longer period of time.
This is the short-term test mentioned above. This test typically lasts anywhere from 2-5 days and we conduct this test under closed building conditions. These closed conditions usually start 12 hours prior to the test and of course remain closed throughout the duration of the test. Our typical procedure is that the testing device is deployed at the lowest level of the home. This test is most commonly used during the resale of a home.
This is the long-term test mentioned above. We conduct this test for at least 91 days, but in some cases, the testing may even take up to one year. Because of the length of testing time needed, we conduct this test under normal lived-in conditions without a special closed building environment. Typically, we deploy the device at the lowest occupied level of home. This method is commonly used outside of real estate transactions. However, it is sometimes used at the basis of an escrow fund release, especially if a short-term test has shown results between 4 and 10 pCi/L.
