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.
