Radon levels change significantly over time. They rise and fall hour to hour and season to season. Concentrations are typically higher in the winter months and its because of the sealing of buildings to conserve energy, the closing of doors and windows creates the reduction in outside air and traps in the radon

Health Canada recommends that homeowners do a long-term radon test, for a minimum of three months, during the fall or winter months and that the detector is placed in the lowest level of the home (where homeowners spend a minimum of 4 hours per day). A three-month test represents a person’s annual average exposure and should be used to determine if a home’s radon concentration exceeds the Canadian guideline level of 200 Bq/m3.

Alpha Track Detector


This is the tracker that we use to complete those 90 day tests. These detectors use a small piece of special plastic enclosed in a container that resemble the pockets in your lungs. The detector is exposed to the air in a home for a specified time. When the radon in the air enters the chamber, the alpha particles produced by decay leave marks on the plastic. At the end of the test the detector is sent to a laboratory for analysis, and the average radon concentration is calculated.

Radon Scout Plus


The Scout is well-suited for both short-term and long-term measurement of radon gas. It is an ideal radon data logger for both radon screening and for mitigation work. This system uses a solid state alpha decay sensor for radon gas that is not affected by temperature, humidity, radon daughters, air currents or gamma radiation levels to ensure accurate and repeatable results. It uses instrument-grade sensors to continually record environmental parameters. This helps ensure test validity and helps in interpreting the results. This is a key piece of equipment during the mitigation process as you will be able to accurately test the results and ensure the equipment is working properly to remove as much radon as possible from the home.

We also utilize this equipment for real estate purchases. As the public receives more education on the devastating affects of radon, we now see an increase in the number of people who require a short term radon test be completed prior to purchasing a new home. In the United States some states are required by law to have a radon test completed prior to selling their home and should the level come in high they are responsible to correct the problems.
