Radscorpions are large, mutated scorpions commonly found in and around abandoned structures. They originated from the North American Emperor scorpion, which were prolific in many pet stores at the time of the Great War. They have since mutated to become much larger, faster and more venomous than ever before. Despite this, various antidotes have been derived from their mutated, stronger venom. Common radscorpions share a similar appearance, with one variant type. However, many sub-populations of unique radscorpion exist.
The radscorpion is a large, poisonous creature that not only deals high damage but it can also poison the player with its deadly venom. Be ready for a good fight if you don't intend on running if you see one of these threatening creatures.
Radscorpions, of all variants, are vicious enemies. They have rock-solid carapaces which can withstand considerable amounts of damage, and their stingers are filled with potent poison. They almost always gather in packs of at least four individuals, and are incredibly deadly to unprepared players.

↑Chris Avellone, Fallout Bible 1 - "The radscorpions are a result of a combination of radiation and the FEV virus, and Razlo in Shady Sands is correct - they were originally Emperor Scorpions that have grown... big."
