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. 

Radon Exposure and Smoking 

Smokers are especially sensitive to radon as their lungs are already damaged. The negative effects of radon and smoking are more than additive, essentially being 1+1=15.7 in terms of relative risk of lung cancer.

  1. Like radon, tobacco smoke contains cancer-causing compounds (carcinogens) that cause DNA damage. The carcinogens in tobacco are different to the particle radiation from radon, and cause different but equally serious types of DNA damage that, over the long term, increase the frequency and severity of genetic mutations.
  2. The DNA damage-induced genetic mutations caused by radon and tobacco together has a greater than additive synergistic effect . on cancer risk, meaning both the chances of cancer and the speed at which a cancer may arise will be higher and faster if a person is exposed to both together.
  3. Both males and females are at risk from the multiplying effects of tobacco and radon. Smokers who are exposed to radon are much more likely to develop lung cancer. It is hypothesized that a huge percentage of smokers might have only developed lung cancer following additional radon exposure.
What the science says:

Recent analysis of multiple different large European radon risk studies indicates that the lifetime risk of lung cancer following 200 Bq/m3 radon exposure increases by a factor of 15.7 if the individual is also a smoker.
