Radon Testing

What is Radon?

Radon is a gas that naturally occurs within the environment. The radioactive gas is caused by the breakdown of uranium found in rock, soil and water. As a gas, Radon is odourless and invisible, therefore being hard to detect in properties without proper tools.

Where is Radon found?

Radon can move through soil and can enter into the atmosphere rather easily. The gas is often released into homes and buildings through cracks in foundation, floors and gaps around piping/cables. Despite radon level maps illustrating high-risk locations, radon can be an issue in any property. Gas levels will be highest within lower levels such as basements but can also be above health standards in any level of a house as well as areas with improper ventilation.

Canadian Radon Standards

Radon gas is measured in becquerels per cubic metre (Bq/m3). Health Canada guidelines for annual concentration for safe occupation of a property is less than 200 Bq/m3. The higher the concentration, the more immediate mitigation should be performed. However, Health Canada also states that lower levels of radon can still be harmful. The government recommends lowering radon levels by as much as possible.

World Standards

Due to increased health concerns, both EPA (Environmental Protection Agency) and the WHO (World Health Organization) have come up with their own guidelines to follow. According to WHO, there are approximately 3,000 annual deaths in Canada caused by radon (lung cancer). The World Health Organization considers any measurement over 100 Bq/M3 to be a health concern. The EPA suggests any measurement over 148 Bq/M3 to be safe.


Living under high levels of radon is proven to be dangerous for you and your family. Radon gas is the second cause of lung cancer in Canada. Radon generates small radioactive particles that when inhaled, can cause permanent damages to respiratory cells. Since most homeowners spend most of their lifetime within the home, long-term damage can occur. Employees in buildings with radon can also be at risk as well. Smokers are also at a higher risk. Symptoms of radon exposure include a chronic cough, chest pain, wheezing, and upper respiratory infections.


Our Services

Why hire a professional? There are hundreds of do-it-yourself kits available online. Without proper knowledge and training, these results can come back inadequate, which can put your family at risk. Additionally, if you are in the midst of a real estate transaction or compliance issues are at stake, you will want to hire a professional contractor to ensure accuracy and transparency.

Our services include both short-term and long-term testing. Short-term testing is often requested to get quick results to prove if there is an underlying issue or not. Short-term testing is recommended in the cases of compliance issues, employee safety, real estate transactions, etc. Long-term testing is the most common type of testing performed. Typically, the test will take 90 days due to radon gas levels fluctuating during each day. Our professionals will ensure the test is places in the proper area for the most accurate reading and will inform the client on how protocol to follow during the months. Unlike do-it-yourself kits, our measurement device is taken to an accredited Ontario Laboratory with results interpreted by our staff for you. Our price of $150 includes initial consultation, radon device setup, extraction, all lab costs and analysis.

Radon Mitigation

When radon results come back higher than the recommended levels suggested, mitigation can be performed. Health Canada suggests that mitigation be performed in a timely manner as any level can cause health issues in the future. Healthy Environmental performs professional radon mitigation services and follows the Canadian – National Radon Proficiency Program (C-NRPP).
