Number of articles about radon in the New York Times

The uranium-238 decay chain

Radon: From Rocks to Lungs

Slide 64

Radon risks are estimated by studying uranium miners

Estimated lung cancer risks from lifetime exposure to radon

Estimated lung cancer deaths
 per year in the US due to radon

In the range 15,000 to 22,000
(~1 in 8 of all lung cancer deaths)

About 85% of these deaths are attributable to radon + smoking

Testing houses for high radon levels
