Radon Testing

Long or short term tests?

Radon testing is broken down into 2 different types of tests; long and short term. Long term testing is for any period greater than 90 days. Short term testing is normally a 2-7 day test with closed house conditions (exterior windows and doors closed with the furnace on auto).
Although Health Canada recommends long term testing for better accuracy, we also offer short term testing which follows the USA standard 48 hour testing procedure. This allows you to make an immediate decision based on the test results to reduce further radon exposure. To begin with a long term test could expose your family to increased levels of radon gas while waiting for the test to be completed. In the USA most testing is for 48 hours.

Many of Canada Radon's clients choose to perform some type of mitigation (reducing radon gas levels) to minimize the radon levels in their home, as even low levels of radon gas exposure can cause lung cancer.

Canada Radon Inc. offers short term and long term radon testing for your convenience. For a short term test we recommend performing a dual test as it provides a more reliable reading. Long term testing can be done as a single test or as a dual.  Simply follow the easy to read instructions and mail out the kit for analysis. The results are usually then forwarded to you, with any recommendations in a few days.

The Corentium radon gas monitor is a state-of-the-art measuring instrument that combines ease of use and performance. The Corentium monitor allows you to take a reading of the radon levels and its LCD screen displays the average daily, weekly and long term concentrations. Powered by 3 standard AAA batteries, the monitor makes it easy to take measurements from one room to another in order to get an overview of the concentrations of radon in a home, workplace, school, a daycare centre or any other location. The Corentium monitor is also an essential tool to use when performing property inspections or when checking the operation of a radon mitigation system. The internal architecture of the Corentium monitor comes from advanced technology normally reserved for commercial-type detectors. Particular attention has been paid to the quality and protection of the internal components, allowing the use of algorithms for signal analysis that are more sophisticated. The Corentium monitor quickly adapts to its environment and eliminates inaccuracies related to external factors, allowing it to obtain the best accuracy in its niche. The Corentium monitor is guaranteed for one year and in normal home use, it requires no annual calibrations throughout its useful life, estimated at over 10 years.
