*- If this is already implemented, then provide better documentation of it.
So I been working on a pack that tries to unify HBM and GT5u as best as I can, and I been wanting to give GT5u's radioactive items the radiation system from HBM, so that it doesn't use the very poor system found in GT5u. However I haven't been able to figure out if you can do that, or if it is possible. So this issue I created to see if it can be added, if it wasn't already.

I now have a few ideas on how it can be implemented
One Option is to go with the ProjectE style of adding commands to make it possible to do it ingame, while also making it possible to reload, but that might require more work.
Another way is to make it a config file, just like all the other config files.
Lastly, there is via CraftTweaker, which might be too outdated for this.
