A complete, professionally managed long-term radon test. We handle the whole process, from placing the detector to explaining your laboratory results, so you get a clear picture of your home's longer-term radon exposure.
Long-term detector
One average for the whole test
At least91 days
Heating season preferred
Radon levels rise and fall from day to day and season to season. A longer measurement smooths out those swings, so it gives a more representative picture of the radon you're actually exposed to.
That's why Health Canada recommends testing for at least 91 days, ideally during the heating season (fall and winter) when homes are closed up. We schedule your test with that in mind.
You don't need to buy a detector, work out where to put it or arrange a laboratory submission. Whether this is your first radon test or you've already had a short-term test, we handle every step and explain the results in plain language.
Quiet Element places the detector at your property.
The detector stays in place, undisturbed, for at least 91 days.
We retrieve the detector and send it to the laboratory.
We explain the laboratory report and possible next steps.
Your laboratory report gives your home's average radon level, which is compared with Health Canada's guideline of 200 Bq/m³ (becquerels per cubic metre). We'll walk you through what your number means.
Below 200 Bq/m³
The health risk is small, but no level of radon is considered risk-free. Lower is always better, and you can still choose to reduce it. If less than 91 days of your test fell in the heating season, Health Canada suggests retesting next heating season.
Above 200 Bq/m³
Health Canada recommends reducing radon in your home within one year. We offer radon mitigation and can talk you through your options.
Well above 200 Bq/m³
The higher the level, the sooner Health Canada recommends taking action. Mitigation should bring radon down as low as reasonably achievable, and a follow-up test confirms it worked.

The measurement takes at least 91 days, and laboratory analysis happens after collection, so your results arrive once the test period ends. A result reflects the conditions while the detector was in place, which is why we follow Health Canada guidance on placement and timing.
We start a 48-hour preliminary check with a professional radon monitor and place a long-term laboratory detector at the same visit. You get an early snapshot within days, while the long-term test builds the clearer picture of your home's average radon level.

Good to know
We set up a Wi-Fi connected continuous radon monitor in your home, on loan for a full year, and send you a report every month so you can follow how your radon levels change through the seasons. At the end of the year, we pick the monitor up.
