Less radioactive erebite

[Roomba]

Thanks to the new material system, erebite is now incredibly, ludicrously radioactive. Even while wearing an industrial suit, you still accumulate radiation damage slowly from erebite,  and anyone standing around erebite items racks up lethal amounts of radiation very quickly in seconds. There's no real way to handle it safely, and scattering a few hidden erebite items around makes for a very quick death for anyone in the vicinity. It's yet another obstacle to handling a mineral that was already extremely rare and inherently volatile.

While we're at it I don't think plasmastone needs to be radioactive either, for much the same reasons.
