Uranium Ore

Uranium Ore spawns in the overworld between 0 and 24 Y. It spawns in 6 clusters per chunk by default, and spawns a maximum of 5 ores per cluster. It is not radioactive.

It drops itself.

When exposed to the radiation of a nuclear or dirty bomb, it has a 1/100 chance to turn into Schrabidium Ore. If it does not turn, it will become "scorched", which cannot be converted into Schrabidium but can still yield uranium.
