Short Term Radon Test
Another option for radon testing is possible using the Corentium Pro measuring tool. Fast, reliable, and much more detailed than the Accustar radon test kit, this short-term radon test takes 28 to 72 hours to complete and is certified by a CNRP-P professional.

This radon testing method requires that a technician come to your home to install the device and pick it up after the test period. While this method is a bit more expensive than the Accustar radon test kit, it allows for a more complete analysis of the radon concentrations in your home. The Corentium Pro is also approved by the National Radon Proficiency Program in Canada.

Before ordering a test, familiarize yourself with the process of setup, laboratory analysis, and interpretation of results. We can also offer you a turnkey service and take care of the tests for you for your peace of mind.

Installation, return to laboratory and report

What does this set of tests contain?

It contains:

  • Instructions and a data sheet;
  • A return envelope;
  • An alpha trace type dosimeter in a clear plastic bag.
Do not open the sealed bags before the start of the test

1. Choose the Parts to Test

Health Canada recommends taking measurements in the occupied area (refers to any place where a family member spends more than four hours per day) of the lowest level of the house. Suitable places for measurement include family rooms, living rooms, playrooms, and bedrooms. The bedrooms are to be preferred since the occupants spend more time there than other places. Do not test kitchens, laundry rooms, bathrooms, crawl spaces, furnace rooms or closets.

  1. Start the test
  2. Check the expiration dates of the devices. Start your test before the expiration date or the results are not valid.
  3. When you are ready to start the test, open the sealed bag that contains the black dosimeter and discard the bag. As soon as you open the bag, the dosimeter becomes active, and the test has started.
  4. Do not remove the VOID sticker or open the dosimeter, otherwise your results will be invalid.
  5. Write each test number and the postal code where the test is performed at the bottom of this instruction sheet and on the data sheet. Do not use the two stickers on the dosimeter, as they are for laboratory use only.
  6. Write the test start date on the data sheet.

2. Place the dosimeters

The ideal place to install the dosimeter is near an interior wall in normally breathed air, between 0.8 m and 2 m (3 ft to 6.5 ft) from the floor, but at least 20 ” (50 cm) from the ceiling and 8 ” (20 cm) from other objects. These measurements are intended to ensure normal air circulation around the dosimeter. The dosimeter should also be placed approximately 40 cm (16 in) from an interior wall or approximately 50 cm (20 in) from an exterior wall. Dosimeters can be hung or placed flat face up or face down. Leave the dosimeters in the same place, avoiding handling them, for a minimum of 91 days and a maximum of 365 days.

3. Complete the test

After at least 91 days, record the test end date and other required information on the data sheet.

Place the dosimeters in a “Ziplock” type bag.

4. Quickly return the dosimeters with the data sheet to the laboratory

Make sure the data sheet is complete. Place the sheet and dosimeters in an envelope to be shipped.

Dosimeters should be sent back to us at RadonXPro, 1440 Ste-Catherine O, Montréal QC H3G 1R8. If possible, use the return envelope provided with your test set.

Checklist for a successful test

  1. Did you follow all the instructions and completely complete the data sheet?
  2. Have you kept a record of your device numbers and the zip code of the tested property?
  3. Have you placed the dosimeters in a “Ziplock” type bag?
  4. Did you send your dosimeters with the completed data sheet to the AccuStar USA laboratory soon after completing the test?

Return address: 1440 Sainte-Catherine O, suite 330, Montréal (Qc)  H3G 1R8

What is radon testing?

Radon testing is the process of testing a building for radon with a radon gas detector such as the Accustar radon test kit or the Corentium Pro short-term radon test. Radon testing is an important factor in a building’s inspection because it can be a significant health hazard if it is not taken care of.

How much is a radon test?

Radon test kit prices vary between 34.99$ and 69.99$. In Canada, Alpha track radon test kits are preferred over the activated charcoal test. The cheapest tests are charcoal activated and are the least reliable. Alpha track tests such as Accustar radon test kits are very reliable and accurate. 


For these kinds of tests, the difference in price relies on shipping fees. Most long-term radon test kits must be analyzed in laboratories located in the United States. Radon test kits require special custom clearance which is easier to obtain through a radon specialized companies or organizations selling radon test kits. You might want to consider paying extra to avoid the shipping hassle and extra fees. Some municipalities give out free radon tests in Canada or refunds. Find out if your city is one of them by going to your city’s website. 

Short-term radon test prices go from 24.95$ to 1 445$.  According to a 2019 research report from the University of Calgary, at-home short-term test kits are not effective at measuring radon concentration. In Canada, short-term testing must be completed by a certified C-NRPP professional using Airthing’s Corentium Pro device, which is also certified by the C-NRPP, the National Radon Safety Board, and the AARST.

How to test your house for radon?

There are two options to test your home for radon. If you are taking the Corentium Pro short-term test, Radon XPro handles everything. 

If you are using a long-term Accustar Alpha track radon test kit, the first thing to do is to choose the room to test. Pick a room that is the closest to ground level and a room where a member of your family spends more than 4 hours a day. Place your dosimeter in an elevated area to have a sample of the air people breathe in the room. Leave the dosimeter for at least 91 days by keeping the interior of the home as airtight as possible. Read the full instructions here.

How accurate are radon tests?

The long-term Accustar Alpha Track radon test kit is the most accurate radon test on the market, while the Corentium Pro short-term test, has a margin of error of about 5%. Even if it is less precise than the long-term radon gas detector, it is still a good indicator of the presence of radon gas in your home.

How often should I test for radon?

If you tested for radon under the Canadian threshold of 200 Bq/m3, you might still want to consider testing your home again, every 5 years. However, if you’ve recently tested for radon near 200 Bq/m3, you should monitor radon concentrations in your home more closely and do an annual radon test.
