Over the years it is becoming more important to not only check your home for Carbon Monoxide but also for Radon Gas. Just like Carbon Monoxide, Radon is odorless and tasteless but it differs in the side effect because if exposed to high levels long term, a person would have a higher risk of developing lung cancer especially smokers. According to Health Canada, Radon Gas is the second leading cause of lung cancer after smoking. Roughly 16% of dealths from lung cancer where tied in with Radon Gas.
Radon Gas is naturally produced from uranium found in the soil and rocks and it exudes through the ground. Health Canada states that all most all homes have radon because they touch the ground. There are so many passages for the Radon to seep through and travel such as the dirt floors, cracks in the foundation walls & floors, basement drains, sumps, spaces & gaps around pipes and concrete walls because they are so porous. Steps can be done to prevent these gateways in to your home. There are testers that you can buy for under $100. Call a professional if your home reads over 200 Bq/m³ (Becquerel’s per cubic meter) which is the Canadian guideline.
If you bought a new home, Tarion has also taken note and they have extended the warranty period to 7 years to submit a claim if the level is 200 Bq/m³ or over.
