The presence of radon gas in the air is the second leading cause of lung cancer. Live with peace of mind.

There is a simple solution for reducing the presence of radon in your home.


Act now to protect your health and the health of your loved ones!


Radon pre-mitigation measurement


After the installation of the dosimeter, the results will be analyzed in the laboratory and we will implement the mitigation processes, if necessary. We also perform a post-mitigation follow-up, to validate the amount of radon after the mitigation. If necessary, we offer you a turnkey service for rapid radon gas measurement.

radon gas mitigation


At your request, following the reception of the results, our team can move quickly to make the installation of the mitigation measures of radon. These measures can be installed in a single day.

The post-mitigation test


We guarantee post mitigation measurements of less than 100 Bq/m3. We perform a post-mitigation test the following winter, which validates that the radon concentrations are below the desirable threshold.

Radon pre-mitigation measurement


Radon Evolution specializes in the measurement and mitigation of radon gas. The company is certified by the NCRP-C (National Radon Competence Program in Canada), and a member of the ACSTR (Canadian Association of Radon Scientists and Technologists).


Radon gas is a phenomenon that is increasingly talked about in the media, in order to raise awareness of its impact on our health. Did you know that since 2008, Health Canada has declared the month of November, Radon month?

RADON: a natural gas

Radon is a natural gas from the decay chain of uranium 238. This odourless, invisible and inert gas escapes from the ground and infiltrates houses through cracks, drains or pipes.

… and radioactive

Radon is a radioactive gas that contributes to the risk factor of developing lung cancer. It is estimated that radon is the 2nd cause of lung cancer development  after tobacco and is responsible for nearly 3000 deaths annually in Canada.


Health Canada‘s radon gas exposure threshold standard


Health Canada has set the MAXIMUM de concentration threshold at 200 Bq/m3 (becquerels per cubic meter).

What is a harmful level of exposure?
  • 100Bq/m3 = Max. exp. per day / World Health Organization
  • 200Bq/m3 = Maximum exposure / day
  • 300Bq/m3 = 1 x-ray / day
  • 370Bq/m3 = 1 pack of cigarette / day
Are you at risk?

The people most at risk from radon are children and inactive people over 55 years of age.

Radon gas concentrations above Health Canada‘s acceptable limit can be found in both new and older buildings. The Quebec building code does not impose any mitigation measures, unless a house is located in an area identified by Health Canada as being at risk. Although Health Canada has identified areas at risk of exposure, radon gas can be found almost anywhere in Quebec.

If your house is well insulated or if your house has a direct opening to the ground (in the case of a house with a crawl space or an earthen cellar, for example), it is at greater risk of being exposed to harmful concentrations.


Telecommuting and radon

Spending more time at home while telecommuting increases the risk of being exposed to radon. Now more than ever, it is important to measure the radon concentration in your home with a dosimetre or a continuous reader with our rapid test service (approximately 7 days).

Measurement and mitigation service

Radon Evolution’s professionals offer you a turnkey service to ensure that you have an accurate picture of the air quality in your home. Following the obtaining of the results of the laboratory or the rapid test, we set up mitigation processes according to the structure of your home.
