Does anyone have ideas how to make radioactive attribute to the uranium... ?
Uranium isn't radioactive in game (98% sure).
That's what he's asking for, he want's it to be radioactive. It would require some C# coding to do such a thing but I'm not sure the best way do it.
Oh, I misread. You can try to go into mods and open a request for it.
We have TV in Rimworld, why go for radio? :D
