[ RadSafe ] Salsman warning

Sun Apr 11 07:19:02 CDT 2010

	I recall that when I worked with the radiation protection branch of  
Health Canada in the 1970’s, we were interested in the health hazard  
to uranium miners. At that time the problem of radon exposure to the  
miners was confounded by the fact that they all smoked heavily. Since  
then I’ve been a nuclear medicine clinician and am not up in the  
relevant literature. Does anyone know if it has been possible to  
differentiate between the effect of smoking and alpha exposure in the  
miners?
