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


Find 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.


Implant Y-3 removes radiation taken when drinking dirty or irradiated water, soft drinks, and alcohol from the Pip-Boy inventory.

The amount of radiation removed is dependent on the player's current radiation It has a lesser effect when drinking from irradiated faucets, toilets/urinals and water ponds. Radiation effects are lowered to +1 rad. The message "Implant Y-3 removed ingested radiation" will appear on-screen, unless drinking from a faucet toilet/urinal or pond.


  • Due to the way the perks' 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

    • 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.
