Hello; Quick question for anyone who knows a bit about radiation... So, Io puts out a lot of gas which turns into plasma and forms a torus around Jupiter. Jupiter's magnetic field and spinning causes the plasma to move along the torus at 74 km/s. Would individual particles like this, traveling at 74 km/s in extreme trace amounts, act as a type of radiation that would necessitate radiation shielding for a manned spacecraft within the torus? The particles in this case would be ionized sulfur, oxygen, sodium, and chlorine. For the purposes of a book I'm writing, I'm curious if the effects would be different for any other elements, such as nitrogen, hydrogen, and helium... This is in general physics, because although the circumstances are astronautical, the question itself has more to do with radiation than astrophysics. Thanks.
