David Saint-Jacques: Have you ever heard of neutron radiation?
It occurs in space when charged particles collide with physical matter, like the walls of the International Space Station . . . and that collision produces neutrons.
These neutrons can penetrate deep into human tissue . . . and cause long-term health problems.
Radiation is much more intense in space than it is on Earth because our planet protects us from most of the rays.
