Radicool

The mod replaces the radiation behavior of NukaCraft: Fallout with a rework. Each rad removes 0.1% of maximum health, and a player who gains a total of 1000 rads dies of radiation poisoning. Lost maximum health is shown in the Fallout-style interface that NukaCraft uses, so the effect is visible on screen. Consumable items now carry rad values updated to match Fallout 4 and Fallout 76.

Two configuration options control the rework: keepRads, which defaults to true or false depending on the setting, and maxRespawnRads, an integer that defaults to a range of 0 to 999. Shielding, and wearing a hazmat suit, still reduces the rads a player gathers. Using a dosimeter shows the rad count to the player rather than the sievert dose. The mod also adds two new gamerules. Radicool supports Mekanism's radiation, and non-player entities that interact with Mekanism radiation are affected too.

The mod is built for Forge and runs on 1.20.1 only, with 0.1.1 as the latest file, published 2026-08-12. Servers that run it need every player to install it too. NukaCraft: Fallout is required, and Mekanism is optional. It is released under All rights reserved and is not open source.
