RadioIsotopes

by Eli4207

RadioIsotopes brings radioactive materials, ore generation and multiblock machines to Fabric worlds, along with lead armor against radiation.

FabricClient and serverMIT LicenseOpen source1.18.2 – 1.19.2

What it does

Uranium, plutonium and other radioactive materials are processed in machines such as the uranium centrifuge and the plutonium reprocessing plant, which are built as multiblock structures. Lithium ore generates only inside diorite, uranium ore mostly inside deepslate, and lead and bismuth ore mostly inside stone, so prospecting depends on the stone type a player digs through. A physicist structure can be found in the world and is where players can buy centrifuges and reprocessing plants.

Radiation is a hazard in this mod, and lead armor and lead blocks are the way to shield against it. The mod also has an industrial casing, a reactor that can explode if it is run carelessly, and a set of decorative and functional items. Installation needs EMI and Fabric API. The mod runs on the client and server, so the server and every player need it. Its code is open source under the MIT License, and files are published for 1.18.2 and 1.19.2.

Key features

  1. Multiblock processing

    Uranium centrifuges and plutonium reprocessing plants are assembled as multiblock structures to process radioactive materials.

  2. Ore by stone type

    Lithium, uranium, lead and bismuth ore each generate inside a specific stone, which shapes where players search for them.

  3. Radiation shielding

    Lead armor and lead blocks protect players from radiation, and the mod includes an industrial casing for machine construction.

  4. Physicist structure

    A physicist structure can be found in the world, where players can buy centrifuges and reprocessing plants.
