ABSTRACT
The director of the Environmental Protection Agency's (EPA) Office of Radiation Programs has claimed that some 20,000 lung cancer deaths arise each year due to radon gas. William Mills, former head of EPA's radiation standard setting division, claims that the figure is misleading. One wellrespected consultant believes that if you take out that portion of disease related to smoking, you are only talking about 300 deaths per year. Further, if new data on an apparent threshold of effect at low exposure levels is taken into account, the effect could be even smaller.1
