The Geiger counter is an essential tool for surviving in the wasteland, allowing the user to monitor the ambient radiation and their own rad count.[1][2]


Wattz C-Radz Geiger counter


A simple device manufactured by Wattz Electronics to detect the presence and strength of radiation fields, such as gamma radiation.[3] Includes a carrying handle and a modern, durable shell for increased portability and ease of use.[4] It's battery life is displayed in the Interface bar's ammo meter.

Pip-Boy Geiger counter

From at least the Pip-Boy 2000 Mark VI onwards, all models of the RobCo Industries Pip-Boy had a miniaturized Geiger counter integrated into the outer shell of the device, with most models having a small mechanical counter near the top left of the screen and a more detailed radiation count within the condition tab.

Behind the scenes


  1. The Vault Dweller: "{125}{}{What would I need a Geiger counter for?}"
    Jake: "{127}{}{What do you need a Gieger counter for!? [Laughs] Though it's been 80 years or so since the bombs fell, there's still radiation around, you goof. You can't see it, never could, but it's there. Heck I'm willin' to bet you got some counts on you now. Everyone that lives in the wastes has a few RAD counts.}"
  2. The Vault Dweller: "{134}{}{How does a Geiger counter work?}"
    Jake: "{138}{}{It's pretty simple, actually. You use it and it tells you how many Rads you have. As long as you keep your Rad count under 100, you should be fine. Go above 100 and you're in some trouble. The worst part is you won't even know you've been sucking up Rads until a few days later. Get over 1000 and you're cooked - unless you get a hold of a whole lot of Rad-Away.}"
  3. Fallout 2 Official Strategies & Secrets: p. 80: "The Geiger Counter is just the thing when you're not sure if the area you're in will make you glow in the dark. Activate the Geiger Counter by placing it into one of your active slots (hands) to see if you're being cooked by gamma radiation, which makes it easier to know when to pop a few Rad-X."
