It is all about your family's health and taking action to ensure that radon gas - a potential killer , is not in your home or business at excessive levels. Since radon gas is radioactive and invisible, odourless and tasteless, you cannot detect it with your senses, The only way to detect this is to MEASURE THE RADON GAS CONCENTRATION by a professional or DIY test kit. Either way, get it measured.
Why should I be concerned with radon gas ?
Exposure to high levels of radon can lead to potentially fatal lung cancer. It is the second leading cause of lung cancer, after smoking, in North America. In Canada 16% of lung cancer deaths (3, 200 people) annually are attributed to radon. Children are most vulnerable and face a lifetime of exposure at home, daycare and or school. Your beloved pets are equally susceptible. The breathe the same air as you do.If you are a smoker or in a smoke environment, the risk of radon-induced lung cancer increases by 900%.  
           Great reason to quit, good reason to test !
