How do you know if there is radon in your home?

The only way to know for sure if there is radon gas in your home is to get a test done by a qualified inspection company, such as AmeriSpec. There are two types of tests; a short-term test which is 48 hours in length and a 90 days test which is highly recommended by Health Canada. With either of these tests, the device must be removed from the home for analysis and a report will be issued to you indicated the level of radon in the home and whether work should be done on your home to reduce the level of radon.
