Radon is colorless, odorless, tasteless radioactive gas. Radon escapes from the ground and can enter enclosed space, such as your home. Sometimes it can concentrate into high levels and contaminate the air you breathe.

Because almost all homes have some radon,  Health Canada recommends that every home and building in Canada should be tested.

Several methods can be used to measure radon in your home.

Methods to control the level of radon in your home vary considerably in their complexity, long-term effectiveness and cost. Many radon control measures require installation by certified contractor.
