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 an implant perk in the Fallout: New Vegas add-on Old World Blues.

Obtaining

The implant must be purchased from the Sink Auto-Doc for 12,000 caps, which requires both installing it via finding its personality module in the Y-17 medical facility and finding the implant module in the Z-9 Crotalus DNA preservation lab.

Effects

Gaining this perk grants a permanent passive ability that reduces the amount of rads inflicted when drinking dirty or irradiated water, soft drinks like Nuka-Cola, and alcohol from the Pip-Boy inventory. It also has a secondary effect when drinking from irradiated faucets, toilets, urinals or water ponds where their rads amounts are lowered to 1 rad.

Notes

  • A message, "Implant Y-3 removed ingested radiation" will appear on-screen when the perk is activated.
  • The amount of radiation removed is dependent on the player's current radiation resistance level.
  • 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. [verification needed] 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.
  • The perk can serve as an alternative to Lead Belly, albeit this perk does not affect irradiated food.

Behind the scenes

The perk image is the same one used for the RobCo processor widget, a quest item in Fallout 3 as well as that of all other implant perks and Implant GRX in Old World Blues. It is also the only perk image in Fallout: New Vegas to be missing Vault Boy or Vault Girl.
