About alpha track technology:
Alpha track radon testers measure alpha particles which are produced as radon radioactively decays. When released from the radon, the alpha particles travel at high speed and impacts a special plastic strip inside the radon test device. The plastic strip is made of purified CR-39 suitable for radon detection. The alpha particle impacts create a visual pit or etches a track in the plastic strip. In the lab, the plastic strip is analyzed using computer-aided imaging technology to determine the number of pits and tracks. From this, the radon concentration required to etch the plastic strip can be calculated.
How the radon test works:
- After completing your order, we will ship a kit to you that includes:
- the radon test device in a sealed bag,
- a datasheet,
- an envelope with a pre-addressed return shipping envelope.
- You remove the radon test device from the sealed bag and deploy it in your home according to the instructions.
- Record the start date, device number and postal code on the datasheet.
- After at least 91 days:
- put the radon test device in a sealed ziplock bag,
- fill in the rest of the datasheet, and keep a separate note for yourself of the test device number — you will need it later to retrieve your results
- return both to the radon test lab in the return shipping envelope provided.
- You will need to pay the shipping cost to return the shipping envelope to the lab (approximately $10)
- The lab will send the results to you within two weeks via email, and the results will be available on their website
Detailed instructions can be found here.
Guidelines for radon test duration:
The health risks of radon depend on the long term radon concentration that you are exposed to in your home. So the radon test you perform should be trying to get the best estimate of that long term exposure. The problem with this is that radon levels are constantly changing:
- Radon levels can vary significantly hour by hour and day by day. A two-day result this week can be very different from a two-day result next week
- Radon levels vary seasonally. The levels are typically higher in winter than in summer – often much higher
So it is important to perform a long term test to average out the highs and the lows, and the winter and summer.
For this reason, Health Canada recommends:
- The optimal test duration is 12 months
- For test periods less than 12 months, the test period should include a mix of seasons
- If only testing for 3 months, the ideal period would be during the typical heating season, between October and April
- The worst time to perform a 3 month test is in the summer
- Don’t make a decision to mitigate radon in your home based on test periods of less than 3 months
Guidelines for placement of radon test devices:
Health Canada makes recommendations for where and how radon test devices should be located:
- Place the radon test device in the lowest level of the home that is occupied for at least 4 hours per day.
- Place the device at least:
- 80 cm above the floor
- 50 cm away from the ceiling or an exterior wall
- 40 cm away from an interior wall
- 20 cm away from other objects to allow airflow around the device
- Measurements should not be made in kitchens, bathrooms, laundry rooms, closets, cupboards or crawl spaces
- Avoid locations where the radon test device will be subject to air currents, such as heating and air conditioning vents
- Avoid locations near heat sources, in direct sunlight, or near electrically powered equipment
Interpreting your results:
The Health Canada action level is 200 Bq/m3.
- If your radon concentration is less than 200 Bq/m3, Health Canada does not recommend remedial action
- If your radon concentration is between 200 Bq/m3 and 600 Bq/m3, Health Canada recommends remedial action be taken within 2 years
- If your radon concentration is above 600 Bq/m3, Health Canada recommends remedial action be taken within 1 year
