“How to die on the way to Mars“
“Space is Radioactive!” were words spoken by a junior researcher at the dawn of the Space Age. The Van Allen radiation belts had just been discovered, now over sixty years ago. How can a “vacuum” be radioactive? Magnetic fields trap high energy particles, shielding us from them while making a radioactive zone near our planet. When we venture beyond this protective shield, we take risks of a solar radiation storm, and a steady, known hazard from galactic cosmic rays. To make matters worse, mass must always be reduced in spacecraft, yet it is the best protection against radiation. This talk will look at the science behind radiation hazards, which is a bit different from that in the comic books. The sad conclusion is that we are likely to see people die in space unless this hazard is taken seriously.
