[ RadSafe ] Diesel exhaust and underground mining vs other factorsfor lun...

The lung cancer incidence in the US is about 160,000. Of these lung cancers 
 about 140,000 are due to smoking and another 20,000 due to radon. Radon is 
the  second leading cause of lung cancer.

To answer my own uncertainty, "In  the United States, smoking 
is estimated to account for 87% of lung cancer  cases (90% in men and 
85% in women)."

Eighty seven percent of 450,000 is 391,500 lung cancer 
deaths  per year from smoking.

The estimate  quote is from Wikipedia and is sourced (fn.  23).
