Question 1

What is radon?

Accepted Answer

Radon is a radioactive gas that comes from the natural decay of uranium found in nearly all soils. It can enter buildings through cracks in floors and walls, and can also be found in well water.

Question 2

Is radon common in Canada?

Accepted Answer

Yes, radon is a common issue in Canada, particularly in northern New Brunswick, where approximately 30% of homes have radon levels above the Health Canada guideline of 200 Bq/m³.

Question 3

How does radon enter a home?

Accepted Answer

Radon can enter a home through cracks in the foundation, gaps around pipes and cables, and through well water. It is most commonly drawn into the home through the natural vacuum effect created by the heating and cooling systems.

Question 4

What are the health risks of radon exposure?

Accepted Answer

Radon exposure increases the risk of developing lung cancer. According to Health Canada, approximately 16% of lung cancer deaths in Canada are attributable to radon exposure.

Question 5

How can I test my home for radon?

Accepted Answer

You can have short-term or long-term radon tests performed by a CNRPP certified technician. Short-term tests typically last between 3-7 days, while long-term tests can last for several months to a year, providing a more accurate representation of radon levels in your home.

Question 6

What is the safe level of radon in a home?

Accepted Answer

Health Canada recommends that radon levels in homes should not exceed 200 becquerels per cubic meter (Bq/m³). If the levels are above this, action should be taken to reduce radon levels.

Question 7

How can I reduce radon levels in my home?

Accepted Answer

Radon levels can be reduced in homes by sealing cracks in floors and walls, improving ventilation, and installing a radon mitigation system, such as a sub-slab depressurization system.

Question 8

How much does it cost to reduce radon levels in a home?

Accepted Answer

The cost of reducing radon levels in a home typically ranges from $1500 to $2000 + HST. This cost includes the installation of a radon mitigation system, such as a sub-slab depressurization system, and any necessary sealing of cracks and gaps in the foundation.

Question 9

Are there radon mitigation programs or subsidies available?

Accepted Answer

Some provinces in Canada, including New Brunswick, offer radon mitigation programs or subsidies to help homeowners cover the cost of radon reduction measures.

Question 10

How often should I test my home for radon?

Accepted Answer

Health Canada recommends testing your home for radon every two years, especially if you have made renovations or changes to your home's foundation or heating system.
