Radon Levels

What Is Your Home's Radon Level?

Radon is a radioactive element that is odorless, colorless, tasteless, and completely undetectable by normal means. It is often found in concentrated forms in buildings, and could be present at unsafe levels in your home right now.

At Maple Leaf Radon Defence, our certified radon mitigation specialists can test your home for radon — and, if necessary, help you control radon infiltration in your home. If you'd like to learn more about radon in your home, contact us by phone or e-mail today, and we'll put you in touch with our local, certified, radon specialist in Ontario.

How Radon Enters Your Home

Greater Toronto's certified radon contractor

In gas form, radon will enter a home from the soil, finding its way through cracks, crevices, dirt floors, around pipe penetrations, through the pores of the concrete itself, and other pathways.

Air is drawn upwards into your home through the "stack effect", which refers to the upward movement of air in a home as it exits through the attic and upper levels.

If there is radon in the soil around your home, it will begin to be concentrated inside your home — particularly in the winter, when your home is sealed shut. If radon becomes concentrated at unsafe levels, it can become a serious health issue for everyone living there.

Radon is found in every state and any home can have elevated radon levels. Testing is the only way to find out if you have a radon problem in your home. Contact the experts at Maple Leaf Radon Defence to schedule a radon test. If the test reveals unhealthy levels of radon, we can then install a radon mitigation system to help lower radon concentration. Contact us today to ensure a healthy home!

Radon Test Results — What Do They Mean?

Radon measurements are reported in becquerels per cubic metre (Bq/m3) — the lower the number, the healthier your home. However, all radon is toxic, and even "small amounts" of radon are not healthy. The good news is that most homes can be mitigated, lowering the levels of radon to some degree.

Health Canada has set the standard of 200 Bq/m3 as the "action level", at which mitigation is recommended. In other words, if your test shows a radon level of 200 Bq/m3 or higher, a mitigation system needs to be installed right away to reduce the numbers to a less toxic level.

Radon concentrations can vary greatly across Canada, with a cross-Canada survey reporting that outdoor radon levels ranged from 11.0 Bq/m3 to 60.7 Bq/m3. The indoor air average is much higher, at about 83.3 Bq/m3. While this number is well below the recommended action level, it is already at a toxicity level that's many times greater than it is outdoors. The World Health Organization (WHO) reports that any concentration of radon is unsafe.

As long as your home is below 200 Bq/m3, you should have some peace of mind. However, Maple Leaf Radon Defence wants to do everything possible to get the radon levels as low as possible. Contact Maple Leaf Radon Defence today for more information.

What Are The Experts Saying About Radon?

"Most radon-induced lung cancers occur from low-and-medium-dose exposures in people's homes. Radon is the second most significant cause of lung cancer after smoking in many countries."
– Dr. Maria Neira, World Health Organization

How to Better Understand Radon Levels

Maybe 370 Bq/m3 doesn't sound all that bad, so 148 Bq/m3 can't be a problem at all. In order to understand the number, you have to understand the measuring system.

Let's compare a few figures.

  • 148 Bq/m3 level of radon has radiation levels equal to the radiation from 100 chest x-rays
  • Most hospitals allow only four chest x-rays annually. That's 5.92 Bq/m3 per x-ray and 23.68 Bq/m3 each year
  • 37 Bq/m3 is the equivalent of 2.5 cigarettes daily

That Said: Can you understand why the WHO has their action level set at 100 Bq/m3?
