CanSAR was founded in 2005 by Elizabeth Hoffmann, who was diagnosed with stage IIIA lung cancer in 2003 at age 37. Liz had never smoked and had no family history of lung cancer. When her home of over 15 years was tested for radon, the results showed a level more than twice the U.S. EPA’s “take action” level of 4 pCi/L.
