A paper out of the Harvard School of Public Health makes the claim that “Unconventional oil and natural gas development” will increase “ambient particle radioactivity” down wind. More simply, fracking will increase radon down wind. They are wrong on two counts: First, they find the increase in radon by trying multiple models until they get a publishable result, multiple testing and multiple modeling or MTMM, aka p-hacking. Second, any increase in radon is very small and higher levels of radon are actually beneficial to humans, e.g., decreases in lung cancer.
