Radiation
Looking for details on how to protect from hazardous radiation? See: Guide: Material Safety
This page refers to radiation as a whole, for block-based/environmental radiation, see Environmental Radiation, for item based radiation, see Item Mechanics.
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 is a key part of producing energy, but it can also be very deadly. This page will explain what the effects of radiation are, and what the player can do to protect themselves.
Exposure
Radiation intake can be come from:
- Radioactive items.
- Chunks containing radioactive blocks, like Radioactive barrels or nuclear waste blocks.
- Consumption of radioactive items like Nuka cola or Radium coffee.
- Nuclear explosions.
- Green Ooze.
- Forgetting to cover your RBMK columns with cover lids like a total дебил.
- Radon gas, usually produced by mining uranium ore.
Radiation sickness
If the player absorbs some radiation, they will suffer the effects of radiation sicknes, which gets more severe the higher their absorbed dose is.
- <200 RADs: No effects will occur below this level
- 200 RADs: Nausea and weakness are applied at random intervals for five seconds, vomiting (hunger level 20 for 3 seconds) occurs every 60 seconds
- 400 RADs: The weakness effect becomes stronger and slowness is added
- 600 RADs: Slowness and weakness reach level 3, and poison 2 may rarely occur. The player now vomits blood every 30 seconds instesd of 60
- 800 RADs: Poison reaches level 3, and wither 2 may apply, which may be deadly even on lower difficulties
- 1000 RADs: Instant death. An achievement is acquired mentioning the player's passing by radiation poisoning and Marie Curie's similar fate
Some mobs may be affected differently by radiation:
- At 50 RADs, Cows will mutate into Mooshrooms
- At 200 RADs, Creepers have a 1:3 chance of turning into Nuclear Creepers, otherwise they die instantly. Ducks will evolve into Quackos The Elder One
- At 500 RADs, Villagers will turn into regular Zombies, which prevents them from being healed back into Villagers
Protection and treatment
Some of the items and blocks that provide protection or treatment against radiation include:
- Geiger counter
- Dosimeter
- Radaways
- Rad-X
- Radiation Absorbers
- Protective armor (basic or vanilla armor pieces do have radiation resistance, albeit a small amount)
- Armor claddings, and some other Armor Mods
- Player decontaminator
Notes
- Exposure from chunk radiation will only decrease as the entity moves away to other chunks, moving above or below a source in the same chunk as the entity doesn't affect radiation exposure
- There is a more accurate radiation system called PRISM, in which some blocks, like concrete, can actually shield from some radiation when covering the source. It can be enabled in the mod's configuration file (hbm.cfg)
- Radiation clouds, dead grass particles, and glowing mushrooms do not emit radiation
- Radiation clouds start to appear if there are over 100 chunk RADs present, and get denser and denser the more irradiated the chunk is
- NTM radiation is measured in RAD or Radiation Absorbed Dose
- When in the inventory, the Tungsten reacher will reduce the player's exposure from radioactive items down to the square root of their original radiation value
