I read about radon to my husband and dog. We wish that dogs could be trained to detect radon!

I bought an electronic radon monitor to test my home. Once I’m done, I’ll loan it to friends and family members so they can test their homes as well.

I purchased a radon test from the Evict radon study. Now I get to test and learn about my home's radon levels while also helping with learning about the science of radon in Canada!

I played the Radon Game on Knowvember.ca and I got all the questions right! I then shared the image on social media to let my friends and family know they should test their homes for radon!

What is Radon?

Radon is a gas that you can’t see, smell or taste. Radon comes from the ground, and can be found at high levels in some buildings. This is dangerous because breathing in high levels of radon for a long time increases the risk of lung cancer.

All homes have some level of radon gas, the question is – how much? The only way to know is to test.
