As a point of information: the elevated incidence of lung cancer in uranium miners is generally attributed to inhalation of radon daughter products that were in high(er) concentrations in the uranium mines than they are in ambient air. The exposure to radiation from the uranium is, at worst, a minor contributor. It is also of note that smoking (combined with radon exposure) is considered a far worse cancer initiator.
