Imagine having a killer lurking in your home. It’s silent, invisible and odourless. Even worse, it could be the leading cause of lung cancer. This killer is none other than radon gas. Radon is a radioactive gas that can enter your home and accumulate to dangerous levels. In this article, we will explore the risks associated with radon, how it enters your home, and measures you can take to protect yourself and your family.
What is radon gas and how does it get into your home?
Understanding the properties of radon
Radon is a colourless, odourless, and tasteless radioactive gas that exists naturally in the environment. It is derived from the breakdown of uranium in soil, rock, and water. The gas travels to the surface, where it can enter buildings through cracks and gaps in the foundation, floors, or walls. Once inside, the radon gas can accumulate to dangerous levels.
The main sources of radon in a home
The primary source of radon in your home is contact with the soil. The gas can seep into your home through cracks and gaps in the basement or foundation. However, it is not only basements that are prone to elevated radon levels. Radon can enter any space that is in contact with the ground, such as crawl spaces and first-floor rooms. Another source of radon is the breakdown of uranium in water. If you use well water or have a private water supply, it is essential to test for radon to ensure that your drinking water is safe.
Why basements are at higher risk of radon gas exposure
Basements are at higher risk of radon gas exposure due to their proximity to the ground. When radon enters your home, it will typically accumulate in the basement first. This is because basements are typically poorly ventilated, and radon gas can’t escape quickly. With prolonged exposure, radon gas levels can reach dangerous levels, putting you and your family’s health at risk.
Why is radon gas dangerous for your health?
How radon exposure can lead to lung cancer
Exposure to radon gas is the leading cause of lung cancer in non-smokers and the second leading cause of lung cancer overall. When radon gas is inhaled, it can damage the cells that line the lung, leading to cancer over time. The longer you are exposed to radon, the higher your risk of developing lung cancer becomes.
Radon gas exposure and the increased risk for smokers
Smokers are at an even higher risk of developing lung cancer when exposed to radon gas. This is because smoking causes damage to the cells in the lungs, making them more susceptible to the harmful effects of radon gas.
Long-term effects of radon gas exposure on your health
Long-term exposure to radon gas can lead to significant health problems, such as lung cancer, especially if you are a smoker. Inhaling radon gas can also damage the cells in your respiratory tract, causing chronic respiratory problems, such as coughing, wheezing, and shortness of breath.
How do you test your home for radon?
Importance of radon testing in homes
Testing your home for radon is the only way to know whether your home has elevated radon levels. Radon testing is essential because it can help you take the necessary steps to reduce your radon exposure, protecting you and your family’s health.
Radon testing methods and tools available
There are two primary types of radon testing: short-term and long-term testing. Short-term testing involves taking measurements for about three months, while long-term testing involves taking measurements for one year or more. Both types of testing are relatively easy to perform and typically involve placing a detector in a room in your home.
Where to place radon detectors in your home
It’s best to place radon detectors in the lowest level of your home where you spend the majority of your time. Typically, this is a basement or a first-floor room. Be sure to follow the manufacturer’s instructions when placing your detector. Testing should be repeated every few years, even if previous tests showed no elevated levels of radon.
What are the recommended actions for reducing radon levels in your home?
How to interpret radon test results
Radon levels in Canada are measured in Becquerels per cubic meter (Bq/m3). If your radon test results show that your home has levels above 200 Bq/m3, it’s important to take steps to reduce the radon levels. If the levels are between 100 Bq/m3 and 200 Bq/m3, Health Canada recommends taking action to reduce the radon levels.
Radon reduction techniques and technologies available in Canada
Several techniques and technologies are available in Canada for reducing radon levels in your home. The most common technique is active soil depressurization, which involves installing a pipe in the ground beneath your home’s foundation to draw the radon gas out and vent it outside.
How to find certified radon professionals for mitigation and reduction
For radon mitigation and reduction, it’s best to find a certified radon professional. The Canadian National Radon Proficiency Program (C-NRPP) certifies professionals who are qualified to test for and reduce radon levels in your home. You can find a C-NRPP-certified professional in your area through the Canadian Association of Radon Scientists and Technologists (CARST) or directly through C-NRPP.
Radon in Canada: What you need to know
Health Canada’s guidelines and recommendations for radon exposure
Health Canada has set guidelines for safe radon levels and recommends taking action if your home has elevated radon levels. The guideline for radon levels in homes is 200 Bq/m3 or less.
Radon levels in different parts of Canada and provincial regulations
Radon levels can vary significantly across Canada, with some parts of the country being at higher risk of elevated radon levels. In Quebec and Saskatchewan, for example, homes are more prone to elevated radon levels due to the prevalence of uranium in the soil. Some provinces have regulations in place to protect residents from radon gas.
Radon scientists and technologists in Canada working on radon awareness and reduction
Many scientists and technologists in Canada are working to raise awareness about the dangers of radon gas and reduce radon levels in homes. The Canadian Cancer Society, for example, is working to promote radon awareness and encourage Canadians to take action to reduce their radon exposure.
