What is Radon?

Radon is a radioactive gas that that forms the breakdown of radium, which is a product of decaying uranium.  It can be found in finished and partially finished basements as well as in your kitchen, if you have granite countertops.

Can radon be detected?

Radon is a lot like Carbon Monoxide, in that it also is a colourless, odourless  gas.  It naturally occurs in rocks, soil and water, it can rise up into homes through gaps in the foundation, drains, pipes, sump pumps and other openings.

Is radon exposure dangerous?

Radon exposure can cause serious health problems because it  can enter into the lungs and can cause severe damage to the lung tissue due to the release of energy from the radioactive particles.   The amount of radon release is similar to that of undergoing hundreds of x-rays every year.

Are there long term risks to radon exposure?

While in small doses, exposure to radon may be harmless.  Radon exposure over a long period of time can increase a person’s risk of developing lung cancer.

What is a dangerous level of radon in my home?

Radon levels above 200 becquerels per cubic metre are considered dangerous and should be remedied within a two year period according to Health Canada.

Can I remove radon from my home?

Health Canada recommends that you consult with a certified radon professional to determine the best radon reduction method.  Repairs can run anywhere from $1,500 to $3,500.
