Radon and Why Is It Dangerous

One of the benefits of spray foam insulation in Victoria is its radon-blocking properties. But exactly what is radon, and why is it so dangerous?


This naturally occurring gas is produced by the breakdown of uranium in soil, water, and rock. It is odourless, colourless, and tasteless, which makes it very difficult to detect. Unfortunately, radon is also a known carcinogen. In fact, according to the Environmental Protection Agency (EPA), it is the leading cause of lung cancer among nonsmokers.

So how does radon get into your home? Well, as the Government of Canada explains: “Radon can enter a home any place it finds an opening where the house is in contact with the ground: cracks in foundation walls and in floor slabs, construction joints, gaps around service pipes, support posts, window casements, floor drains, sumps or cavities inside walls.”

The EPA recommends that all homes be tested for radon, and if levels are found to be above 4 picocuries per liter of air (pCi/L), corrective action should be taken. The good news is there are a number of ways to reduce radon levels in your home, including sealing cracks and installing a radon mitigation system.


One of the best ways to prevent radon gas from entering your home is to make sure it is properly insulated. Spray foam insulation in Victoria creates an airtight barrier that can help keep radon and other pollutants out.
