revert mining changes

[cyberTripping]

Mining still has pods, been doing mining in my spare time as CE. Only play on 1 though, so maybe it's different there. I'm pretty sure radioactivity is blocked by the industrial armor, but I couldn't produce it even with supposedly the right materials (koshmarite, bohrum, clarentine) so who knows. I exposed myself to a stack of erebite when transporting it for a second (moving it from a pod to a crate) and it was enough to kill me, so there's that.
