WHAT IS THE CURRENT CANADIAN GUIDELINE FOR RADON IN INDOOR AIR?

     The current Canadian guideline for radon in indoor air for dwellings is 200 Becquerels per cubic metre (200 Bq/m3 ). This was recently reduced from 800 Bq/m3 based on new information about potential health risks. A Becquerel means one radioactive disintegration per second. Individual dwelling owners may wish to reduce radon levels as much as they reasonably can, using methods they find affordable and practical. However, the level in a dwelling should not be above the new guideline. The risk for a non-smoker at 800 Bq/m3 is higher than all common accidental deaths (motor vehicle accidents, drownings, falls, fire and more) combined. We take precautions against accidental deaths by putting on our seatbelts, wearing lifejackets or ensuring that our smoke detectors are working – we should also be testing our homes for radon!

WHAT ARE THE RADON LEVELS IN CANADA?

Radon is found across Canada, because it occurs naturally in soil. Concentrations differ greatly, but are usually higher in areas where there is a higher amount of uranium in underlying rock and soil. Some amount of radon is found in almost every home, but concentration levels will vary from one house to another, even if they are similar and next door to each other. It is expected that only a small percentage of homes will have radon levels above the guideline but the ONLY way to be sure of the radon level in your home is to TEST.

HOW CAN RADON GET INTO MY HOME?

    The air pressure inside your home is usually lower than in the soil surrounding the foundation. This difference in pressure draws air and other gases, including radon, from the soil into your home. Radon can enter a home any place it finds an opening where the house contacts the soil: 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. 

Rival Home Inspections does only the Radon testing…We DO NOT mitigate Radon. You need to avoid companies that do both the testing and the mitigation. At Rival, we believe it’s a conflict of interest to do both. Protect you family and hire us to help you. Once the mitigation process is complete, we'll do a short term measurement to confirm that the process was successful.

Heath Canada recommends that Radon Measurements be conducted by only certified members of the Canadian Nation Radon Proficiency Program (C-NRPP)

Short Term (2 - 4 Days) :  $325               Add-On to Home Inspection: $275

  •  Ideal for real estate transactions or to verify an installed radon mitigation systems is working properly

  • May be used to obtain approximate strength of radon

  • Quickly identify buildings with elevated radon concentrations.


Long Term (3 months - 1 year):  $325           If Following a Short Term test: $200

  • Produces a more accurate measurement

  • Long Term testing is recommended by Heath Canada and is the only test recognized by Tarion for warranty claims 


* Short Term tests are never acceptable to determine radon concentrations for purposes of assessing the need for remedial actions.
 * A single short-term measurement is not a sufficient basis for a decision to mitigate. In this case a
follow-up measurement is always necessary for mitigation decision-making regardless of the
initial measurement result.







What Is Radon

    Radon is a radioactive gas that occurs naturally when the uranium in soil and rock breaks down. It is invisible, odourless and tasteless. When radon is released from the ground into the outdoor air, it is diluted and is not a concern. However, in enclosed spaces like homes, it can sometimes accumulate to high levels, which can be a risk to the health of you and your family

What are the Heath Effects of Radon?

     Radon gas breaks down or decays to form radioactive elements that can be inhaled into the lungs. In the lungs, decay continues, creating radioactive particles that release small bursts of energy. This energy is absorbed by nearby lung tissue, damaging the lung cells. When cells are damaged, they have the potential to result in cancer when they reproduce. Exposure to high levels of radon in indoor air results in an increased risk of developing lung cancer. The risk of cancer depends on the level of radon and how long a person is exposed to those levels. Exposure to radon and tobacco use together can significantly increase your risk of lung cancer. For example, if you are a lifelong smoker, your risk of getting lung cancer is 1 in 10. If you add long‑term exposure to a high level of radon, your risk becomes 1 in 3. On the other hand, if you are a non-smoker, your lifetime lung cancer risk at the same high radon level is 1 in 20.
