ItemSprites.png Uranium Block (Rarity: 1)

This block might be slowly making you sick. Surely there are better things you could be building with. Maybe you can blast a hole in it, instead...?

Use a(n) ItemSprites.png Geiger Counter.

The Uranium Block is an unsplicable solid foreground block. One can be obtained from locating a radioactive source with a Geiger Counter in GEIGERHILLS.


Placing a Water Bucket on a Uranium Block and using a Nuclear Detonator on it can let players fish exclusive radioactive items from it.

Below is a list of items which can possibly be made by combining a stack of Uranium Block with 2 other stacks of items.

  • The game does not count the Uranium Block as an actual radioactive item, and thus, it won't remove the Geiger Counter's alive status.
    • Obtaining an Uranium Block doesn't count toward any goal revolving around finding items with the Geiger Counter.
  • The fact that a Water Bucket and a Nuclear Detonator can be used on it for radioactive fishing is referenced by the description of the Uranium Block.
