how we measure radon gas

Radon gas Measurement

Radon Gas Expert completes Radon Measurements in homes, daycare facilities, schools, workplaces, and multiple unit residential buildings consistent with the specific testing protocols and quality assurance guidelines developed in conjunction with Health Canada. Our testing devices are not radioactive and do not pose any hazards to users or occupants.


we follow health canada guidelines for 100% accuracy

We complete short term tests for real estate transactions and certified long term tests for accuracy and Tarion Warranty purposes as recommended by Health Canada. Elevated Radon Gas concentrations can occur in any building regardless of age, heating system, foundation type, geographic location, air tightness, or building materials used. Certified long term testing is the only way to definitively determine Radon Gas levels.

our steps

we use the best protocols

Long term (91+ days) Radon Gas testing provides the most accurate representation of the annual average indoor Radon Gas concentration within a building. Radon Gas levels can fluctuate significantly over the short term due to environmental factors such as wind and precipitation.  Ideally the Radon Gas testing period will include winter months as Radon Gas levels can be significantly increased during the heating season due to the stack effect.


Step 1

In heating season warm air within the structure rises and escapes through the attic to the outside of the structure. Replacement of the escaped air occurs naturally to equalize the internal air pressure.


Step 2

More radon gas enters structures during winter months as frozen ground and ground snow cover creates a barrier for soil gas which is percolating through the path of least resistance. The vacuum created by the stack effect effectively suctions Radon Gas.


Step 3

Additionally, closed, airtight houses increase the stack effect as window and door openings for fresh air are typically kept closed throughout the heating season.

let our team test your home & business for radon Gas

Radon Gas accounts for approximately 56% of our annual radiation exposure (200-360 millirem per year) and is the second leading cause of lung cancer. Lung cancer typically reduces life expectancy by 15 years so effective, proactive, low cost management to protect your family is critical.
