Re[2]: Radon in the News -Reply

     In Colorado there were reports that the U miners who were at increased 
     risk for lung cancer were those who smoked in the mines.  Those who 
     smoked, but not in the mines, appeared to have risk similar to 
     non-mining smokers.

In answer to your question regarding uranium miners and smoking.....
     
     
     The health effects due to radon progeny are derived mainly from 
     studies of lung cancer in underground miners in the U.S., Canada, 
     Sweden and Czechoslovakia.  Studies of the human health effects of 
     radon have several limitations.  The main limitations of which concern 
     weak estimations of exposure and the complicating role of smoking in 
     the causation of the lung cancers observed in miners.  Only the U.S. 
     uranium miner study contains relatively complete smoking histories.  
     In that study 3/4 of the miners were smokers.  Of the 383 cases of 
     lung cancer observed in the U.S. study, 356 (93%) occurred in smokers 
     and 25 occurred in non-smokers (the smoking
