Sorta, seeing as how regeneration doesn't trigger vanilla death events meaning NC doesn't clear the radiation from the player until they just die, regardless of the config settings

We all (well, presumably we do) know how 10 went to 11, seeing as he saved Wilfred's life at the cost of his own due to radiation poisoning.
Well, that's the problem with NuclearCraft + This mod.
With IC2 it's simple enough, as radiation is just a potion effect that gets cleared upon death. However, IC2's radiation also sucks, because it's just the Wither effect when you think about it, only you get it from an item.
NuclearCraft's radiation is a bit more advanced, and also allows you to set custom item radioactivity, except regeneration doesn't clear radiation afterwards, as NC's radiation is a separate counter rather then a potion effect.
This might be a bit complicated, and I totally understand that, especially since NC may or may not be getting an overhaul soon.
If you don't want this in the mod, feel free to close this entry.

PS. This might sound dumb, especially since I just realized I might be missing some sort of lore about a Time Lord being able to just die to a certain type of radiation (although I don't think any of the ores in NC would emit that.)

I was just wondering about this for a pack. Guess I shouldn't add NC just yet.

Started looking into this

Expect this to be implemented next version :)

Okay, thanks!

I will look into it, but I'm not going to be making any promises
Trying to focus on getting 1.14 stuff up to speed, but keep finding myself going back to 1.12 things

This won't be making it to 1.12.2 unfortunately, if that mod is on 1.14, I will consider this.
