What is radon?

Radon is a gas formed by the breakdown of uranium, a natural radioactive material found in all soil and rock.

How can radon harm my lungs?

As radon breaks down, it forms radioactive particles that can get lodged into your lung tissue as you breathe.  The radon particles release energy that can damage the cells in your lungs. When the cells in your lungs are damaged, there is the possibility of developing lung cancer. Radon is the second leading cause of lung cancer!

How can radon enter my home?

Most of the time the air pressure inside your home is lower than the pressure in the soil surrounding your home’s foundation. This difference in pressure can draw air and other gases in the soil, including radon, into the house. Gas containing radon can enter your home at any opening where the house contacts the soil.  These openings can be present even in well-built and new houses.

How do I test for radon?

Testing is easy and inexpensive using radon test kits. Radon levels in a home change over time. They can increase and decrease from one day to the next. For this reason, testing over a longer period of time is most accurate. Health Canada recommends homeowners do a long-term radon test (for at least three months) during the fall or winter. Place the detector in the lowest area of the home where you or a member your family spends on average four hours each day. Testing instructions are included in your test kit.

Can radon levels be reduced in my home?

Techniques to lower radon levels are effective and can save lives. Radon levels in most homes can be reduced by more than 80% for about the same cost as other common home repairs such as replacing the furnace or air conditioner.  To help you find the best way to reduce the radon level in your home, find a radon mitigation (reduction) expert who has been certified under the Canadian National Radon Proficiency Program (C-NRPP).
