WHO releases new radon guidelines co-authored by Angell

On September 21, 2009, the World Health Organization (WHO) called for stronger action against indoor radon, the leading cause of lung cancer among US and Canadian non-smokers. The WHO recommendation calls for lowering radon levels by one-third below current US guidance.

"The WHO recommendations more strongly emphasize the importance of radon testing by all home owners and home buyers and reduction of high concentrations of the radioactive gas," says Bill Angell (Housing Studies), president of the American Association of Radon Scientists and Technologists (AARST), in the WHO media release. "The World
Health Organization's strong stand is based upon new evidence of the risk
posed by toxic radon," added Angell from the 2009 International Radon Symposium.
