The month of November is dedicated to raising awareness about the dangers posed by radon, a naturally occurring radioactive gas found in rock, soil and water. It can be trapped inside homes where it builds up in the air over time, causing an increased risk of lung cancer.
All types of houses can have elevated radon levels, including older homes, new builds, as well as both drafty and well-insulated homes. A radon test kit is the best way to measure the level of this gas in your home. Health Canada suggests testing for 3 months during the heating season, which makes November an ideal time to get your kit.
There are 2 types of radon test kits: Short term kits test for radon for 2-90 days, while long term kits test for over 90 days to provide your home's year round average radon level. The Canadian guideline for radon in indoor air is 200 Becquerels per cubic metre (200 Bq/m3). If your test measures a higher level, consult with a certified radon mitigation professional to help you find the best way to reduce the radon level in your home.
When should you test for radon?
- if it's never been tested, or levels are unknown
- before and after doing any renos that convert an unfinished basement area into living space
- after making any repairs to reduce radon levels
- when preparing to buy or sell a home
Ways to reduce radon levels in your home:
- increase airflow by opening windows and using fans and vents to circulate air
- seal cracks in floors and walls
- when buying a new home, inquire about radon protective measures
Let me know if you have any questions about measuring the level of radon in your home.
