Radioactive Containment

Radiation Meter
The Radiation Meter detects nearby radiation zones without requiring the player to already be inside one.
The detector reacts according to the distance from the zone's edge:
Over 100 blocks — silent
100–51 blocks — slow beeps
50–21 blocks — faster beeps with increased pitch
20 blocks or less — rapid, higher-pitched beeps
The meter uses client-side sound playback synchronized through server packets, ensuring that only the player using the detector hears the signal.
Radiation Zones
Radiation zones are generated deterministically from the world's seed, allowing the same world to always generate the same radiation locations. Radiation begins at Y=60 and extends upward, while underground areas remain protected from the radiation system. Each zone has an irregular polygon shape rather than a simple circle and can have one of three danger levels:
![]()
Danger Level 1 - 100 points.
Danger Level 2 - 200 points.
Danger Level 3 - 300 points.
Radiation detection is based on the distance from the actual edge of a zone, allowing the Radiation Meter to become increasingly active as the player approaches danger. It will be shown in the right top corner when danger is approached.
Radiation Damage
Players inside radiation zones take periodic radiation damage based on the zone's danger level and their total Radiation Protection Points.
Radiation uses a custom damage type that bypasses conventional armor, enchantments, resistance effects, and shields. Only dedicated radiation protection can reduce the resulting damage.
Radiation also damages specialized radiation armor over time, regardless of Unbreaking, eventually destroying equipment that remains exposed for too long.
Radiation Armor
The mod adds two protective equipment tiers:
![]()
Radiation MK.I
25 Radiation Protection per piece
100 Radiation Protection for a full set
![]()
Radiation MK.II
75 Radiation Protection per piece
300 Radiation Protection for a full set
The armor can be mixed between tiers to create different protection levels. Both armor sets can be repaired using Uranium Ingots.
Environmental Effects
Radiation affects the appearance of the environment.

Water inside radiation zones becomes visibly radioactive with custom green still, flowing, and water-overlay textures, while normal water outside radiation zones remains unchanged.
Radiation zones also produce a static visual overlay and danger indicator showing the current radiation level. A matching static radiation sound plays while the player remains inside a dangerous zone and stops immediately after leaving it.
Passive Creatures
Radiation is not limited to players. Passive creatures exposed to radiation also receive periodic radiation damage, including animals, water animals, ambient creatures, and villagers.
Hostile mobs are unaffected.
Uranium
Uranium Ore generates naturally in the Overworld and can be processed into Uranium Ingots.
![]()
Uranium Ore supports:
Silk Touch
Fortune
Normal ore drops
Uranium-based crafting and equipment repair
Crafting System
The mod includes a custom shaped-recipe system that supports exact ingredient quantities per crafting slot.

This allows recipes such as:
2 Uranium Ingots in a single slot
3 Uranium Ingots in a single slot
Exact quantities of Iron and other materials
Tag-based ingredients such as any color of wool
The system uses normal Minecraft crafting tables while extending them with per-slot ingredient counts.
Radiation Manual
A Radiation Manual is provided as an in-game reference guide.
The manual contains nine recipe pages covering all major radiation equipment and tools. Recipes are rendered directly from the mod's actual recipe data using Minecraft item models and textures, so no static recipe screenshots are required.
New players receive the Radiation Manual and an introductory radiation information message when they first join the world.

Radioactive Containment is designed around the idea that radiation should feel like an environmental threat rather than simply another status effect: something the player must detect, prepare for, and respect while exploring the world.
