But we really don't know that, because no studies have been done using this equipment. In addition to concerns that the radiation, while lower in total than that absorbed during a flight, is absorbed over a much smaller volume of tissue, adequate validation that the machines can't break in dangerous ways hasn't been performed (and even the most basic detection mechanisms for failure such as having the operators wear dosimeters have been neglected or banned outright). It violates every principle of radiation safety.
