Radon Inspections

Radon is a naturally occurring radioactive gas. According to Health Canada, certain levels of radon trapped in the home can pose a risk of lung cancer. The risk increases for smokers.

Radon is formed when radium disintegrates and can be found in the ground and in the air. Outdoors, the gas poses little threat because the total accumulated amount is relatively low. However, indoors in basements and in crawlspaces, the gas can built up, reaching unsafe levels. Because it is a gas, it can seep into the home from the ground through any porous surface, including dirt floors, concrete and small cracks.

Are Your Home and Family at Risk?

Radon can be a problem in all types of homes and has been found in homes in every region, including old homes, new homes, drafty homes, insulated homes, homes with basements and homes without basements. Radon can enter a home through the following areas:

  • Cracks in solid floors
  • Construction joints 
  • Cracks in walls
  • Gaps in suspended floors
  • Cavities inside walls
  • The water supply

Protect Yourself

According to the U.S. surgeon general, radon is the second leading cause of lung cancer in the United States today. The U.S. Environmental Protection Agency (EPA) recommends that all homes be tested for radon, regardless of geographic location, because of the link between radon and lung cancer.

The EPA also recommends the following:

  • If you are buying or selling a home, have it tested for radon.
  • For a new home, ask if radon-resistant construction features were used and whether the home has been tested.
  • Mitigate the home if the radon level is 4 picocuries per liter (pCi/L) or higher.
  • Radon levels less than 4 pCi/L still pose a risk, and in many cases, can be reduced.

Hire a Qualified Radon Tester

Testing is available to determine if radon levels in your home exceed the government standards. Certified inspectors will place activated charcoal canisters on the lowest level of the home. The canisters remain for several days before being picked up and transported to a lab. The lab measures the amount of radioactivity absorbed and determines the average level of radon for the testing period. A written report is provided to the client.

It is important to get an accurate test. The best way to assure this is to hire a qualified professional, often a home inspector, to conduct the radon testing. A qualified tester knows the proper conditions, test devices and guidelines for obtaining reliable radon test results. Contact your local NPI inspector today to obtain reliable radon test results

In June 2007, a new guideline for safe Radon levels was implemented across Canada. The new guidelines set a safe Radon level at 200 bequerels per cubic meter – a guideline four times more stringent that the old one.

If more than 200 bequerels per cubic meter is uncovered, mitigation is warranted. This may include sealing basement floors and walls, or providing better ventilation to move the Radon out of the home.

Reduce Radon Levels in Your Home

Since there is no known safe level of radon, there can always be some risk. But the risk can be reduced by lowering the radon level in your home.

There are several proven methods to reduce radon in your home, including the following:

  • Sealing cracks and other openings in the foundation
  • Installing a mitigation system with a vent pipe and fan to prevent radon gas from entering the home from below the concrete floor

The cost of reducing radon in your home depends on how your home was built and the extent of the radon problem. Most homes can be mitigated. The average cost is about $1,200, although this can range from $800 to $2,500.
