The simplest one: battery, display, no app.
Battery-powered continuous monitor showing 7-day to 1-year averages in Bq/m³.
Two families of detectors exist: the passive dosimeter, exposed for at least 91 days, and the electronic monitor, which displays a reading in real time. Both count as a long-term measurement — the monitor under two conditions: C-NRPP-approved, and left in place for 91 days or more.
There are two families of detectors: the passive long-term dosimeter and the continuous electronic monitor. The long-term dosimeter (also called an alpha-track) is the most widespread reference: a small sensor with no battery and no screen. You expose it at home for 91 days or more, then mail it back to a laboratory. The laboratory reports the average concentration in becquerels per cubic meter (Bq/m³). (Health Canada)
The continuous electronic monitor displays the concentration in real time, with its history: the tool for checking that a mitigation is doing its job, or for exploring. Health Canada recognizes both families for the long-term measurement: C-NRPP-approved and left in place for 91 days or more, a monitor counts as a long-term measurement. The models presented below are C-NRPP-approved. Only few-day readings remain indicative: they are no substitute for an average established over time. (C-NRPP)

C-NRPP-approved and left in place for ≥ 91 days, they count as a long-term measurement too — Health Canada recognizes both device families. Continuous tracking on top; only few-day readings remain indicative.

The measurement that counts lasts 91 days or more: the long-term measurement. Radon concentration varies hour by hour and season by season — ventilation, weather, heating, open windows. An honest average therefore takes time. Health Canada recommends ideally 3 to 12 months, preferably during the heating season: the house is closed up, and radon accumulates the most. (Health Canada)
Placing the dosimeter follows simple rules. The lowest room you occupy regularly, at breathing height. Away from drafts, windows, exterior walls and ventilation appliances. Health Canada’s guide details placement for your house’s configuration; follow the instructions that come with your device too. That long-term measurement, reported in Bq/m³, is what the radon map aggregates: sector averages rest on it alone. (Health Canada)
Short-term tests are a glimpse, not a diagnosis. Some devices and services promise a result within days. They render a real service: spotting an obvious problem, comparing two rooms, quickly checking a worry. But they measure the weather of the moment, not the air you breathe through the year. (WHO)
On the map, tests shorter than 91 days are labelled “indicative” and excluded from sector averages: they inform, they do not ground the statistics. A short-term test reporting a high concentration calls for a confirming long-term measurement. A reassuring short-term test does not waive the reference measurement.
It is the laboratory analysis that turns the exposed sensor into a result in Bq/m³: a passive dosimeter says nothing by itself. In Canada, the proficiency of these services is governed by the C-NRPP — the Canadian National Radon Proficiency Program. The C-NRPP maintains the directories of accredited providers and laboratories. (C-NRPP)
Three paths lead to an analyzed measurement. Buying a dosimeter “with analysis included” from a provincial lung association, including the Quebec Lung Association: the result comes back by email or post, depending on the provider. Ordering a detector + analysis kit from an accredited service. Or hiring a certified professional who places, collects and interprets the dosimeter for you. In every case, check that the analysis is performed by an accredited laboratory — the C-NRPP directory is the reference. (C-NRPP)
