RADON TESTING MAY - AUGUST?: 6 MONTH RADON TEST ENCOURAGED  

Thank you for your interest in testing with Evict Radon

Evict Radon is a Canadian non-profit organization dedicated to solving Canada’s significant and worsening radon-gas exposure problem. Radon is a substantial cause of lung cancer even in non-smokers. By testing your home with one of our non-profit, research-grade radon test kits and enrolling in our national, public university-based research study, you are helping Evict Radon-aligned researchers from across Canada to understand radon exposure and develop new ways to protect ourselves and loved ones.

Common practice states that winter is the optimal time to radon test. However, as we collect more data, we have determined little difference between winter and spring radon testing. We do, however, encourage our participants to test over seasonal change. At this time, the best and most accurate radon readings obtained during the spring and summer months are those that are longer than 6 months. 

The majority of cities and towns in Canada have been built on high radon potential soils. This includes the BC interior, the Yukon, the Prairies, the Greater Toronto Area, much of Quebec and the Atlantic province region.

 

What we know: 

  1. Canada is a very large country with many areas of very high radon potential (meaning >300 Bq/kg of surficial geology)
  2. Canada also has strong seasonal fluctuations in weather and temperature –meaning our winters are often very cold, and our summers are very hot. Collectively, this environment causes Canadians to spend a great deal of time inside either artificially warmed or cooled indoor air environments. Such environments have the potential for highly concentrated radon levels.
  3. Without knowing it, Canadians have settled and built our villages, towns and cities on soils with very high radon potential, and we have designed and built houses that are very ‘good’ radon capture and contain devices. Thus, Canadians are among the more radon-exposed populations on Earth.
  4. It is important to recognize that this problem is preventable but, by and large, is no-one’s “fault”.

There have been several recent studies on Canadian radon exposure including:
