Gama rays are not particles. It's our atmosphere what's protecting us, isn't it?
Very few gamma-rays make it through the atmosphere. The atmosphere is as thick to gamma-rays as a twelve-foot thick plate of aluminum. Gamma-rays
are very very unlikely to go through that much material. However, they can strike the material and produce 'secondary' particles which are more
penetrating, and can go through the material.
I've read 120 m of air or 13 mm of lead is enough.
Earth would be affected by electrically charged particles in case of weaker magnetosphere how it is now on poles. I don't know how, it may be crazy
lightning show, northern lights everywhere and who knows what else but no immediate Fukushima.
