C-NRPP Listed Professional Devices

This list includes devices submitted by the manufacturer which have been evaluated to meet a minimum set of established criteria by C-NRPP.

You can find details on the minimum requirements and the approval process here. (link will be added)

All devices listed must also have an approved Analytical Laboratory to ensure that these are used following part of a proper Quality Assurance Program.  For information on the C-NRPP Quality Assurance Plan, please click here. (link will be added)

If you are a C-NRPP Radon Measurement Professional who provides services for deployment & collection of devices without providing the analysis, contact a certified Analytical Laboratory (link).

Measurement duration

Long Term Radon Test – is a radon test which is of duration of 90 days or longer

  • Typical devices for Long Term Radon Test are alpha track and electret ion (confirm with the manufacture of each device or the Device Listing Below)

Short Term Radon Test –is a radon test which is of duration of at least 48 hours but less than 3 months

  • Typical devices for short term radon tests are continuous radon monitors (CRM), Electret Ion (ES), charcoal canisters, liquid scintillation or alpha track (confirm with the manufacture of each device or the Device Listing below)

Device Types:

AT – Alpha track detectors use a small piece of special plastic or film inside a container to provide an average of radon levels over the full duration of the testing period.  The package is opened to start the test and when the test is completed it is sent to the laboratory for analysis. The radon exposure duration can be from 10 days to 12 months.  Verify with the manufacturer the suggested duration for each device.

CRM – Continuous Radon Monitor record real-time continuous measurements of radon gas over a series of minutes and reports the results, generally in hourly increments. These devices will have methods for storing, displaying, and retrieving the data logged by the device and may also have the ability to measure and track additional environmental parameters above and beyond the radon concentration such as temperature, barometric pressure, and relative humidity, and they often have onboard motion sensors.  These devices need to be annually calibrated by the manufacturer.

EL – Electret Ion Chambers consists of a special plastic canister (ion chamber) containing an electrostatically charged disk detector (electret). This type of detector may be deployed for 48 hrs to 12 months.

AC – Activated Charcoal detectors are airtight containers filled with activated charcoal and covered with a screen and filter.  The detector is opened in the area to be sampled and exposed to the air for a specified period of time, and at the end of the sampling period, the container is sealed and then sent to a laboratory for analysis. It is important that the kits be mailed back to the lab with the least delay possible.  These detectors are normally deployed for measurement periods of 2 to 7 days.

LS – Charcoal Liquid Scintillation is a small vial of activated charcoal for sampling the radon.  Following exposure, the vial is sealed and returned to a laboratory for analysis.  It is important that the kits be mailed back to the lab with the least delay possible.  These detectors are also normally deployed for periods of 2 to 7 days.

Note: C-NRPP strongly recommends that a decision for mitigation be based on a long term test as per Health Canada guidance.  C-NRPP acknowledges that Short Term Testing has a place in post-mitigation confirmation, real estate and when a more rapid indication of the radon concentration may be required. All short term tests should be confirmed with a follow-up long term test to have an accurate representation of the average annual long term exposure & before a decision for mitigation is taken.  Please see C-NRPP Statement on Short Term Testing testing here.
