to those of you confused over the hazmat helmet. hazmat suits DO NOT protect you from radiation. you have to be wearing like ten foot thick concrete armor or something to actually protect you. what they do do, is keep it contained in one area. you don't wear the suit everywhere and so when you are near some kind of radiactive material, your not spreading the material all over the place. what can protect you, is a geiger counter, it will tell you if you are getting to close.how do i know this? because my dad worked worked at a nuclear plant, he even did some things that the hazmats refused to do, so i know about this stuff from him.
