This page refers to radiation as a whole, for block-based/environmental radiation, see Environmental Radiation, for item based radiation, see Item Mechanics and Item Radioactivity.
Definition of radiation and info provided on the link
Intro[]
Marie Curie invented the theory of radioactivity, the treatment of radioactivity, and dying of radioactivity. - Achievement: Ouch, radiation!
Radiation is a major part of the mod since it not only is a key part of producing energy but also important for the progression of the player. Setting aside the pros it also has many cons with a major one being, premature death of course. Now, this page will not explain what radiation is (the obvious part) but instead what are its effects and what can the player do to protect themselves.
Exposure[]
Exposure to radioactivity is not always so obvious and can be quite frustrating when the player is not aware of the radiation mechanic the mod introduces. Radiation intake can be caused by:
- Radioactive items.
- Radioactive Blocks like Radioactive barrels or nuclear waste blocks.
- Consumption of radioactive items like Nuka cola or being shot with nuclear bullets.
- Nuclear explosions.
- Green Ooze.
- Forgetting to cover your nuclear reactor with concrete like a total дебил (Russian: Debil, means moron).
- Being a total дебил again and forgetting to put panels on your RBMK.
- Radon gas, usually produced by mining Uranium Ore.
Radiation sickness[]
If the player increases their radiation dose in any way, they are in for some fun.
- <200 RADs: No effects will occur below this level.
- 200 RADs: At 200 RADs, slight nausea will occur now and then. Vomiting and hunger 3 may also ensue.
- 300 RADs: Reaching 300 RADs means that the weakness effect will occur now and then.
- 400 RADs: At 400 RADs weakness will evolve into weakness 2, and the player will get the slowness effect now and then for a few seconds. At this point, survival becomes more challenging since the player can get swarmed by mobs easier due to the slowness and the absence of standard DPS.
- 500 RADs: At 500 RADs, effects caused by radiation poisoning become more intense and appear more frequently.
- 600 RADs: Acquiring 600 RADs results in poison, slowness 3, hunger 4, and weakness 3, forcing the player to rely on ranged choices to survive.
- 800 RADs: At 800 RADs, the player will begin to suffer from the withering effect. At this stage, radiation becomes an imminent threat if the player is in low enough health, usually resulting in death.
- 900 RADs: At 900 RADs withering 1 becomes withering 2. Debuffs will now occur continuously every second. The only ways someone can survive at such a state is by using spider milk, an armor addon that nullifies negative potion effects. Alternatively someone could try wearing an armor with strong buffs like the schrabidium armor to protect from enemies, eating golden apples or using other similar potent healing items often to offset the barrage of debuffs and using a ranged weapon with decent damage that can kill someone's foes before they see them first at such a fragile state.
- 1000 RADs: 1000 RADs means game over by an instant unavoidable death. On the flip side an achievement is acquired mentioning the player's passing by radiation poisoning and Marie Curie's similar fate as well.
Small note: Radiation will also affect nearby mobs mutating some of them; villagers and cows into zombies and mooshrooms, respectively.
Protection and treatment[]
Radiation is very dangerous, but there are many ways you can avoid it or clean an area and yourself from it.
Some of the devices that provide protection or treatment against radiation include, but are not limited to:
- Geiger counter
- Radaways
- Rad-X
- Radiation Absorbers
- Highly protective armors provided by the mod (basic or vanilla armor pieces do have radiation resistance, albeit a small amount)
- Player decontaminator
Notes[]
- Concrete can cover the nuclear reactor but not protect from radiation in any other scenario.
- There is a block-based radiation system in development, and some blocks, like the waste barrels, have this property where surrounding them with concrete does, in fact, protect against radiation.
- Radiation counts equally on an entire chunk from the top to the bottom of the chunk.
- Exposure from a chunk radiation source will only decrease as you move away to further chunks, moving above or below a source doesn't reduce radiation exposure.
- If the player is exposed to taint and red cloud at the same time, the player will then get the "Tainted Heart" effect, granting complete radiation immunity for one hour.
- Radiation clouds, dead grass particles, and glowing mushrooms will not emit radiation.
- Radiation clouds indicate that there are over 100 chunk RADs present.
- Try to avoid these clouds if you ever spot them, they look like green smoke/fog over the ground.
- NTM radiation is measured in RAD or Radiation Absorbed Dose.
- When in your inventory, the Tungsten reacher will reduce your exposure from radioactive items down to the square root of their original radiation value.

Ouch, Radiation!
