Irradiation Unattended is a minecraft mod for Forge 1.20.1 that is currently in the making! With the mod comes the introduction of various new materials, the main focus being Uranium, which is found exclusively in the new Polluted Caves biome... There are also new Trash Blocks, which can be crafted from a variety of mostly useless items. They seem to have the strange ability to multiply when heated, maybe this can be of use...
This mod is still in heavy development, most things will be changed from how they currently are! Mojang Me ( @Silicryt )
