He had me up until the Van Allen Belt. He does not have a grasp of nuclear physics. His take on ionizing radiation is deeply flawed. There can be some serious risk IF a solar event occurs when you are outside of the protection of the Earth, however it is difficult to predict when a solar eruption/flare will take place. It is a gamble, but there are means of shielding and protection that can be taken to minimize risk for many of the smaller solar events.
