Implant Y-3 places an internal filtration system in the digestive tract that strips any liquid consumed of all radioactive particles before being processed by the body.— In-game description

Implant Y-3 is a special perk in the Fallout: New Vegas add-on Old World Blues.


This perk is available to the player after finding the Auto-Doc Upgrade: Implant Y-3 in the Z-9 Crotalus DNA preservation lab. It can then be purchased from the Auto-Doc in The Sink for 12,000 caps.


  • Removes radiation taken when drinking dirty or irradiated water, soft drinks, and alcohol from the Pip-Boy inventory.
    • The message "Implant Y-3 removed ingested radiation" will appear on-screen.
    • The amount of radiation removed is dependent on the player's current radiation resistance level.
  • It has a lesser effect when drinking from irradiated faucets, toilets, urinals and water ponds. Radiation effects are lowered to +1 rad.
    • There is no on-screen message when drinking from these sources.


  • Due to the way the perk's effects are calculated (1 - (Player.GetActorValue RadResist / 100)), it is less effective at higher levels of radiation resistance. Using dirty water as an example:
    • RadResist 15%, drinking dirty water (Rad+5) → no radiation
    • RadResist 69%, drinking dirty water (Rad+1) → no radiation
    • RadResist 70%, drinking dirty water (Rad+1) → radiation +1
      • Note that high levels of radiation resistance may be temporary (boosted by Rad-X and clothing items), while the player may need to drink on a more regular basis, especially in hardcore mode.
  • This perk is an alternative to the Lead Belly perk, but does not affect irradiated food.

    • All Old World Blues implant perks use this image, and they are the only characteristics in the SPECIAL that have no Vault Boy or Vault Girl included in the image.
