Radon Testing


Radon is a radioactive, colorless, odourless, tasteless noble gas, occurring naturally as an indirect decay product of uranium or thorium. As radon decays it produces new radioactive elements called radon daughters. Unlike the gaseous radon itself, radon daughters are solids and stick to surfaces, such as dust particles in the air. When contaminated dust is inhaled, these particles can stick to the airways of the lung and increase the risk of developing lung cancer.  Although radon has a short lifetime, some radon gas from natural sources can accumulate to far higher than normal concentrations in buildings, especially in low areas such as basements and crawl spaces due to the fact that radon is heavier than air.  Radon can enter buildings through foundation cracks, plumbing lines, floor drains or other penetrations in the building foundation.  Radon is considered a significant indoor air quality contaminant worldwide.  According to the United States Environmental Protection Agency (EPA), radon is the second most frequent cause of lung cancer, after cigarette smoking, causing 21,000 lung cancer deaths per year in the United States. Have the air quality in your home or workplace tested by one of our radon testing specialists.
