According to Government of Canada:

The International Agency for Research on Cancer (IARC) has identified radon as a group 1 carcinogen. It is the number one cause of lung cancer for non-smokers in Canada. An individual's risk of lung cancer from radon depends on the concentration and duration of an individual's exposure. As such, individuals with long-term exposure to high radon levels are at greater risk of developing lung cancer.

Radon gas is in all buildings in contact with the ground. Testing is the only way to know the radon level in a specific home and to determine if mitigation is necessary. Health Canada recommends every home should be tested, no matter where it is located, the type of building, or if it already has a mitigation system. Radon can vary widely between homes, even in homes in the same building, or buildings on the same street.

This device is a battery operated detector which records the Radon level over several days and weeks to determine if your location has levels of Radon above or below the safe threshold. Note that the accuracy increases over time, because you have a greater sample size for the average readings. Please use at least 7 days in one location. For maximum accuracy 90 days is recommended.

Radon Level (pCi/L) Interpretation in Canada:

• Under 2 pCi/L = Low, but no level is risk‑free.

• 2–5.4 pCi/L = Elevated; consider mitigation planning.

• ≥ 5.4 pCi/L = Dangerous — mitigation recommended.

• 16.2 pCi/L = Urgent Level: Above these levels, mitigation should be completed within one year.

Just as a comparison to international standards, World Health Organization (WHO): Recommends action at 2.7 pCi/L (100 Bq/m³).
