“The Harper Government is working to keep Canadian families safe from the health risks of radon, the second leading cause of lung cancer,” said Minister Aglukkaq. “You can't see it, smell it, or taste it. The only way to know if you have a radon problem is to test your home.”
“The first year results of this survey reinforce how important it is for Canadians to test their homes,” said Mr. Blaney. “Our Government recommends using long-term test devices for a minimum of three months, in fall, winter and early spring when the windows are closed. If the radon level is high, the problem can be fixed.”
“November is Lung Cancer Awareness Month. Radon is the second leading cause of cancer, after smoking,” said Heather Borquez, president and CEO of the Canadian Lung Association. “Last year, lung cancer claimed the lives of 20,500 Canadians. It’s estimated that about 10 per cent of lung cancer deaths are related to long-term exposure to residential radon. We urge Canadians to protect their loved ones by testing their homes for radon.”
This two-year survey of approximately 18,000 homes, to be completed in 2011, will estimate the number of homes with radon levels above the current Canadian guideline.
Radon gas is produced by the natural breakdown of uranium in the ground. It can get into homes through foundation cracks and openings and build up to unacceptably high levels. Radon levels vary from house to house depending on a number of factors
such as the soil the home is built on, construction and ventilation. While the radon levels in the vast majority of Canadian homes are below the current Canadian guideline, first-year results of the Cross-Canada Survey of Radon Concentrations in Homes indicate that approximately 7% of Canadian homes have elevated radon levels – a number that is slightly higher than originally predicted.
Radon self-test kits are available through the internet from radon service providers and at certain hardware stores. If radon levels in a home are above the Canadian guideline of 200 becquerels/metre³, Health Canada recommends taking steps to reduce the radon level in the home. The higher the level of radon the sooner action should be taken to address the problem. General information on how to reduce radon levels can be found in Radon: A Guide for Canadian Homeowners, which is available on the Canada Mortgage and Housing Corporation’s website ( http://www03.cmhc-schl.gc.ca/catalog/home.cfm?lang=en&fr=1291055289440 ).
Health Canada has an ongoing radon outreach and awareness program that is focussed on raising awareness of radon and its potential health risks, and to encouraging radon testing and remediation.

Radon
What is radon?
Radon is a radioactive gas found naturally in the environment. It is produced by the decay of uranium found in rocks and soil. It is invisible, odourless and tasteless. When radon is released from the ground into the outdoor air, it is diluted and is not a concern. However, in enclosed spaces, like homes, it can sometimes accumulate to high levels, which can be a risk to the health of you and your family.
What are the health risks?
Radon exposure increases your risk of developing lung cancer. It is the second leading cause of lung cancer after smoking. The risk of cancer depends on the level of radon in your house, how long you are exposed and whether you smoke. Exposure to radon and tobacco use together can significantly increase your risk of lung cancer.
How can Radon get into my home?
Radon can enter a home through any place it finds an opening where the house contacts the soil: cracks in foundation walls and in floor slabs, construction joints, gaps around service pipes, support posts, window casements, floor drains, sumps or cavities inside walls.
How do I determine the level of radon in my home?
The ONLY way to know if you have a radon problem is to test your home. It is simple and inexpensive. Health Canada recommends using a long-term test device for a minimum of three months. The best time to test is between September and April when your windows are mostly closed.Radon test devices are available from some home improvement retailers or can be ordered by phone or over the Internet. Radon testing can also be performed by a trained service provider.
How can I reduce radon levels in my home?
If the radon level in your home is above the Canadian guideline of 200 becquerels/metre3, you should take steps to reduce the level. The higher the radon level in your home, the sooner it needs to be fixed.If your home tests above the guideline, here are some ways to reduce the level of radon:
Increase the ventilation to allow an exchange of air.
Seal all cracks and openings in foundation walls and floors, and around pipes and drains.
Renovate existing basement floors, particularly earth floors. Install a radon removal system using a fan and piping to draw the radon from under the home and expel it outside. This is typically done by a contractor and is the most common and effective method of reducing radon levels.
What is Health Canada Doing?
Health Canada has an ongoing radon outreach and awareness program that is focussed on homeowners, commercial building owners, the building industry, and public health practitioners. The objective of the program is to raise awareness of radon and its potential health risks, and to encourage testing and action to reduce levels, where necessary. Health Canada works very closely with regional, provincial, territorial, and national stakeholders to maximize the program's reach to all Canadians.
