Last sentence: "In interplanetary space there is no such protective magnetosphere shielding,” VirtualGathis December 9, 2014 12:39 PM If this thing is riding on the ISS it is of marginal value for analyzing radiation exposure in "space" The ISS is in LEO very close to the atmosphere. That is inside both of the Van Allen belts which deflect charged particles and radiation.Put it in a system at the L2 or Lunar Orbit and I think it would give a better understanding of how much radiation deep space astronauts will endure. As it is it is kind of like trying to get an idea of how much radiation exposure a body would absorb inside a nuclear reactor by measuring exposure in a lead lined bunker next door. William Johnson December 9, 2014 12:59 PM So when will they send this on a trip around the moon or at least far enough out in space to eliminate Earth's protection? justme70 December 9, 2014 02:09 PM "...space travel may be safer than thought"Well then, we'd better stop thinking and start space travelling!

A new species entirely may develop. Don Duncan December 9, 2014 02:44 PM The magnetosphere is our main protection against radiation. Any test done within that protected region is useless. It says nothing about space.

Jesse Jenkins December 12, 2014 06:07 AM What effect does the sun's magnetosphere have on interplanetary radiation exposure, if any? It's much stronger than earth's magnetosphere, albeit we are inside of it. does it only effect interstellar radiation? I wonder if the radiation is less intense between planets since planetary gravity tends to attract massive particles.
