Which test was it?
Short-term test or screeningA few days
Long-term testAt least 91 days
Health Canada's 200 Bq/m³ guideline refers to the long-term average.
Step 1: Check what kind of test it was.
A short-term test or screening shows levels during a few days. Health Canada's guideline applies to a home's long-term average, measured over at least 91 days. If your result came from a short-term test, a long-term test is usually the right next step.
Step 2: If your long-term result is above 200 Bq/m³.
Health Canada recommends reducing radon levels.
