A Response to: Deadly Radon in Montana?

Dr. Hart intended to answer the question of whether or not radon is deadly in Montana. Instead he answered the question, “Do Environmental Protection Agency (EPA) county zone designations correlate to statistically different rates of lung cancer deaths in Montana?” Based on a non-significant student t-test comparing mean cancer mortality for EPA zone 1 and 2 designated counties, Dr. Hart concluded the “notion” that radon is deadly in Montana should be questioned. Dr. Hart’s analysis is flawed.
