How to Check for Radon in Your House 2021

If you’ve been following the news, you have probably seen that in certain parts of North America (and really the world), there are extremely high levels of radon. We just read that in Edmonton, Canada the Lung Association is calling for homeowners to get their homes tested for radon. Since this blog is all about your overall health, we thought it was important to cover this important topic and suggest that everyone gets their home’s radon levels checked.

What is Radon?

According to the American Lung Association, radon is, “a naturally occurring gas that can have a big impact on indoor air quality and your health. You can’t see or smell it, and radon can build up inside homes, buildings and schools to dangerous levels. Exposure to high levels of radon can cause lung cancer.”

The fact that radon can’t be seen or smelled is what makes it particularly scary! Lung cancer that is affected/associated with radon account for approximately 21,000 deaths annually in the United States. (source)

What Are the Health Effects of Radon?

The American Lung Association also states that radon is the second leading cause of lung cancer in the United State (source)

Signs and symptoms of lung cancer from radon exposure can include:

  • Persistent cough
  • Chest pain
  • Fatigue
  • Hoarseness
  • Shortness of breath
  • Wheezing
  • Coughing up blood
  • Often contracting pneumonia and/or bronchitis
  • Loss of appetite
  • Weight loss

How Do You Test for Radon in Your Home?

Now this is the most important part of the article as every house should be tested for radon. You can either go for a short term radon test kit (approximately 2- 7 days) or a long term radon test (approximately 90 days). The only issue with a short term test is it can be less reliable as it’s for a shorter duration of time.

An Interesting Radon Case study from Edmonton, Alberta, Canada where radon levels in Edmonton homes have been found to be extremely high.

Experts are encouraging Edmonton homeowners to test for radon—a colourless and odourless gas that can cause lung cancer and other ailments.

The president and CEO of The Lung Association, Leigh Allard, was shocked when she learned how high radon levels were at her Terwillegar home.

“I understood the risks to radon, but I didn’t realize how high the levels could be,” she told CTV News.

Allard’s house had more than 800 Becquerel of gas—four times the amount Health Canada deems safe.

“Panic and fear went through me,” Allard said, so she called a specialist.

“It’s a risk in every home,” Radon Gas Removal Systems Inc. Owner Bill Elms said. “What we’re finding in Edmonton, this house could be 800, the house next door is tested and it could be 50. It all depends on the fractures of the earth. The gas takes the course of least resistance.”
