You should fix your home if your radon test result is above the guideline of 200 Bq/m 3. Techniques to lower radon levels are effective and can save lives. Health Canada recommends that you hire a mitigation professional certified under the Canadian National Radon Proficiency Program (C-NRPP) ) to help you find the best way to reduce the radon level in your home.

Radon is a naturally-occurring radioactive gas that can cause lung cancer. Radon gas is inert, colorless and odorless. Radon is naturally in the atmosphere in trace amounts. Outdoors, radon disperses rapidly and, generally, is not a health issue. Most radon exposure occurs inside homes, schools and workplaces.

Over time, uranium decays into radium, which then decays Radon dosimetry was done by means of integrated alpha-track measurements over a 1-year period. In the homes monitored, the average level of radon-222 was about 120 becquerels (Bq)/m3 in the bedroom area and 200 Bq/m3 in the basement. Typically, when we speak of radon, we are speaking of radon 222 which has an half life of 3.8 days. This means that if a volume of radon is sealed into a container and left on its own, half of the radon will decay into SLRDs and be gone in four days. it was assumed that drafty houses would have less radon than "tight" houses.

The resulting distribution of annual-average radon-222 concentrations can be characterized by an arithmetic mean of 1.5 picocurie per liter (55 becquerels per cubic meter) and a long tail with 1 to 3% of homes exceeding 8 picocuries per liter, or by a geometric mean of 0.9 picocurie per liter and a geometric standard deviation of about 2.8.

The very short half-life of Thoron (96 seconds) reduces its typical concentration in homes to 0.3 pCi/L.
