Assume that you are in an alien star system. Your ship is currently being hit by a phenomenon called solar overflow, which messes up your electronics and can kill you without good shielding. It is different from solar flares or coronal ejections, as the heat is negligible in comparison to the radiation damage it cause, but it can be a side effect from a solar flare.
What you get is a wave of sudden harmful rays. It's something like a bunch of photons hitting everything and breaking every molecular bonds in its path. For the pilot, the radiation caused by this phenomenon can kill him or make him extremely ill. This can be blocked by a particle or plasma shield.
My question, how can this phenomenon work, how can it occur and what other effects can it have on the ship and its occupants?
EDIT: These are two different shields. Basically, the particle shield works by having the shield emitter placed on various points of the ship firing particles at an approaching matter calculated entirely by the shield's computer after input from the sensors. The human only needs to activate it and the computer does everything as long as both the computer and sensor are functioning properly. Visually, it creates a wall that prevents all matter and particles from hitting the ship at a certain range.
The plasma shields are gaseous plasma that hugs the ship instead of being fired outwards. It blocks all matter, by holding it instead of deflecting it in the same way that ballistic gels hold bullets shot into it. Visually, the ship apears glowing blue or green while the plasma shield is active.
You can't have both because the nature of the shields interfere with each other's operations. If your particle shields fire out particles to block the incoming particle, your particle will be caught inside the plasma shields layer.
