This article is B.S. because they haven't even left earth's orbit with the test. Last sentence: "In interplanetary space there is no such protective magnetosphere shielding,”
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.

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?
"...space travel may be safer than thought"
Well then, we'd better stop thinking and start space travelling!

An interesting posit: When man finally has the technology to establish an off world colony on a permanent basis....those inhabitants according to the law of natural selection, will have to adapt to a different set of environmental variables. A new species entirely may develop.

The magnetosphere is our main protection against radiation. Any test done within that protected region is useless. It says nothing about space.
Radiation levels have been measured outside of LEO and are not deemed to be 'showstoppers' for say ... a return trip to Mars;

they should have gotten this on nasas test of their capsule, it went out farther then the ISS. im sure nasa would have done it for free if they shared the data.

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.
ISS passes through the South Atlantic Anomaly of the Van Allen belt.
