Radioactivity
by neddiebones
Radioactivity adds radioactive blocks and items to Forge for Minecraft 1.20.1, letting uranium be dug from ore and refined into pure uranium.
What it does
Uranium ore can be dug out of the world, and the dust it yields is refined into pure uranium, which opens new possibilities for power and nuclear-themed builds. The mod is built around radiation, so the blocks and items carry real danger if handled carelessly. Radioactivity runs on client and server, so the server and every player need it. Its only published build is for Forge, for 1.20.1, released on 2025-02-08 under All rights reserved, not open source.
Key features

Refining and crafting
Uranium dust is refined into pure uranium, which is then used in crafting recipes added by the mod.
Radiation hazards
Radioactive blocks and items bring risk, so handling them without care has consequences in play.
