Radon

Radon is one of the products produced from the natural decay of uranium.

Uranium is a common element found in rock and soil in this province. Uranium can be a concern in well water due to its health effects, mainly on the kidneys and skeletal system.  Wherever there is natural uranium, radon will be present.  Radon is a concern because it is a colourless, radioactive gas that has no smell, so there is no way to tell if radon is present in your home without using a testing device. Radon exposure increases cancer rates so knowing if you have radon is very important.

Homes built on natural uranium deposits may accumulate radon.  Radon is heavier than air so it normally collects in basements when it escapes out of the ground.  Over time, the concentration of radon gas can reach levels that will present an increased risk of lung cancer.  If you are a smoker, that risk is drastically increased.

High levels of radon were detected during previous testing programs in this province.  A onetime test can give you an accurate warning to the presence and concentration of radon in your home.  These testing kits are relatively cheap and easy to use. Corrective actions can range from sealing cracks in the foundation to adding an air handler unit to dilute radon with fresh air.
