Geiger Counter Keychain

The Geiger Counter Keychain is a compact, single-use style device that detects radiation in the immediate area. It functions as a small radiation detector meant to indicate the presence of nearby radioactive sources rather than measure precise dose rates. In the game it appears as a collectible item you can pick up in multiple indoor and outdoor areas where radioactive contamination or waste is present; finding one provides quick confirmation that radiation exists nearby and can guide exploration or avoidance.

This item is distributed across several levels and sectors, typically placed where the player is likely to encounter contaminated zones or radioactive hazards. It does not alter environmental radiation or interact with mechanical systems; its role is informational and primarily utility-focused for navigation and safety. Because it only senses radiation in the immediate vicinity, carry or use it close to potential sources to confirm contamination.

• Common spawn locations: Cloud Reactor entrance open area (on top of a large crate); Roadway control room above, near radioactive waste; on the ground next to Dr. K. Hill, surrounded by radioactive waste.
• Office Sector: level 3, in the small kitchen area adjacent to the Analysis Office.
• Manufacturing West: on a catwalk above the blue door that leads back to the Office Sector.
• Cascade Laboratories: level 2, inside the Wildlife Pens’ locker room.
• The item is listed among known source locations in the game’s item location references, indicating it can be repeatedly found in the above set of areas.

Practical notes for use and strategy:

• Approach likely contamination points while carrying the keychain; it registers only nearby radiation, so detection requires proximity to the source.
• Because it is small and portable, the Geiger Counter Keychain is best used to confirm suspected hotspots encountered during exploration or when tracking radioactive items or NPCs.
• Check enclosed utility rooms, locker rooms, catwalks above sector transitions, and areas near waste containers—these are the documented placement types for this item.
• The keychain provides immediate situational awareness but does not replace full radiation protection or equipment that mitigates exposure; use it to inform decisions about when to don protective gear or avoid an area.
• If you are trying to complete a collection or checklist, visit the listed locations (Cloud Reactor entrance crate, Roadway control room, Dr. K. Hill area, Office Sector kitchen level 3, Manufacturing West catwalk, Cascade Laboratories locker room) as documented spawn points.
