What do I do when I receive the detector? What is the process?

  1. The Radtrak and Rapidos Alpha Track detectors include a unique instruction sheet and a return envelope. Effective June 1, 2026, a QR code is included, linking to a prepaid label. 

    Note: Each detector must be registered individually using the login details on the instruction sheet. 

  2. When you’re ready to start testing, remove the detector from its plastic wrapping and place it at your chosen testing spot. Follow the instructions to register your detector at radonline.com.

    Note: the detector should stay in this location for the entire testing period.

  3. After testing, log back into radonline.com to update your testing information.

  4. Scan the QR code to get your prepaid return label, then mail your detector to the Canadian Return Hub via Canada Post. Please allow 1-2 weeks in transit.

  5. Once processed, your report will be available for download through your radonline.com login, and you'll also receive a copy by email. Lab analysis takes 7-14 business days.

Do the detectors expire?

Yes, each detector must be deployed before the expiry date on the plastic wrap.

Where is my detector number?

The detector number is the number located on the bottom of your detector. (xxxxxx-x)

Where should I place the detector in my home?

Place at least one test in the least-used area of the home, such as a family room, a recreational room, or a bedroom. Health Canada recommends testing on the lowest lived-in level of your home where you spend more than four hours per day. Click here for additional dos and don’ts.

  • Place the test kit on a shelf or table against an interior wall that is free of ventilation sources, such as vents or air returns.

  • Keep the test at least three feet away from all windows, doorways, and exterior walls. Placing the test in a draft or near a window introduces too much fresh air, which can affect the accuracy of your indoor air measurements.

  • Going in and out of the house won't hurt, but for short-term measurements, keep the windows closed during the test period to ensure accurate readings.

Will the detector still be reading while it is being sent to the lab? Surely this will affect my results?

Our lab professionals use specialized algorithms to ensure accurate analysis based on the testing start and end date you provided online through RadOnline. The average radon measured during transport is included in the calculation.

My Continuous Radon Monitor is measuring in Pci/l. How do I change it to bq/m3?

The factory default settings are in Pci/l; you can change the measurement to bq/m3 in your app settings.

Please send us an email if you are having any trouble

Radon

What is radon?

Radon is a naturally occurring radioactive gas produced by the decay of uranium minerals present in rock, soil and water. Indoors, it is not naturally occurring; you cannot taste, smell or see radon.

Why is radon dangerous?

Radon is radioactive. Outdoors, there is little danger because radon is diluted in the open air. Indoor,s radon is trapped and becomes concentrated in enclosed or poorly ventilated spaces, resulting in a significantly increased health risk, especially lung cancer.

What are the symptoms of radon poisoning?

There are no immediate symptoms of exposure to radon at low, moderate or high levels. Symptoms of illness as a result of radon poisoning include those of lung cancer or stomach cancer. If you are concerned about your health, contact your doctor or a health official who is knowledgeable about the effects of radon.

Can you see, taste or smell radon?

No, the only way to know if radon is present in your indoor environment is to test.

Additional Information

Why should I test for radon?

Protect your health! We rely on public health authorities to tell us the right actions to take for our health. The reality is, ultimately, we are the ones responsible for taking action. We have a duty to protect our indoor air quality for ourselves and everyone who comes into our environment - including pets.   

What are the differences between a short-term and long-term radon test?

A short-term radon test is a screening test to get fast results. An example of this is to get an idea of how much might be held in escrow for a real estate transaction. A long-term test is recommended to inform a mitigation decision. Long-term testing lasts at least 3 months and provides an average radon concentration that can be compared to the threshold defined in the national guideline. 

How long should I test for?

A long-term test of at least 3 months is recommended for accuracy. Testing over the heating season is best when doors and windows are kept closed.

I received my report. What does it mean?

On your report, there is a lot of information: detector number(s), location information, and your results. The main bit of information to look at is your Average Radon Concentration. This is the radon level recorded during the test kit deployment. Next to that number, there will be a +/- number called the standard deviation. This number is the variance in which your radon level may have fluctuated. It will always be a small number and have little to no impact on your average radon concentration, and any decisions on fixing a radon level should be made solely on your average level.

The US and Canada have each set a guideline for radon exposure. In the US, it is 4.0 pCi/l (picocuries per litre). In Canada, the radon guideline above, when action should be taken, is 200 Bq/m3 (becquerels per cubic metre).

I have tested, and my radon levels are high. What do I do now?

Not to worry, we are here to help. Please contact us to discuss your results and mitigation options with one of our C-NRPP professionals.

When is the best time to test for radon?

Anytime is a good time to test. The best time is during the winter or heating season when doors and windows are closed. This will indicate the indoor air quality in your environment. 

How often should I test for radon?

Health Canada recommends radon testing be performed every two years.

Residential testing

When testing a residence, there are many factors to consider. How large is the home? How many floors does it have? Are there multiple areas that make contact with the ground? Which separate rooms are frequented heavily? It is recommended to place a test in the lowest level of the home, any additional level that touches the ground, and any rooms that are frequently used and relatively closed off from the main portion of the level being tested. In most instances, a test will be placed in the basement, any parts of the home on a slab or above a crawl space, and in any bedrooms, offices, etc. that are separate rooms in the basement or on the level being tested. If you are unsure, contact us to help you determine the appropriate number of detectors for your residence.

Buildings and schools 

We suggest following Health Canada’s Guide for Radon Measurement in Public Buildings.

Always test institutions with the guidance of a C-NRPP-certified radon measurement professional.

Multifamily buildings

In multifamily buildings, some regions require certification for testing and protocol in the AARST-NRPP document “Multifamily Building Measurement”, which should be followed.

Why do my radon levels change?

Radon is volatile. It is quite normal for radon levels to change up to a factor of 5 (5 times the initial reading) within one 24-hour measurement. Radon levels can change because of the following reasons:

Changes in:

  • Temperature

  • Pressure

  • Humidity

  • Ventilation

As well as other factors such as:

  • Building insulation

  • Building foundation

  • Snowfall

  • Ice

  • Rain

  • Earthquakes

In addition, no radon test is 100% accurate. Radon levels will also vary due to the inherent uncertainty in each measurement method. 

My dog ate my detector. Should I be worried?

The good news is that our detectors contain no harmful chemicals that would harm this precious member of your family. We imagine the next few days might be a bit unpleasant for your little one, but for peace of mind, please contact your veterinarian for their professional advice.

I have children - where can I put the detector so little hands don’t find it?

Each detector has a small hole at the top so you can pull a string through and hang the device in the air, a perfect solution for those curious fingers in your home!

I am interested in purchasing a bulk order. Who should I speak to?

If you would like to purchase more than 25 detectors, please contact us to discuss bulk order options.

How big is the detector?

Our short-term and long-term Alpha Track detectors are about the size of a hockey puck and are very lightweight.

Are the detectors reusable?

The Radtrak and Rapidos detectors are designed for one-time use only. The lab will not return the detector to you once the analysis is complete. Electronic continuous-use detectors and monitors are available for purchase through our online store.

My detector is still sealed in its package. Does my detector expire?

The Alpha Track detectors should be deployed by the date on the plastic wrap. Do not open the detector’s plastic wrap until you are ready to start testing.

Why do you use a lab located in Lombard, IL?

Analysis labs are costly to set up and operate. For this reason, we have one for North America, which is centrally located on the North American Continent. Radonova’s detectors are proprietary and must be returned to the Radonova lab for analysis.
