Scientist (Fallout 3)

Scientists are unlucky techies found dead across the Capital Wasteland.

There is a wrecked highway south of Raven Rock with a truck on it. If the player approaches the truck, an explosion goes off inside the truck and the body of a scientist flies out the back, off the bridge. He is carrying a Big Book of Science. There is a chance that a piece of his corpse may stay on the bridge, allowing easier looting without running into the mirelurks under the highway. (Using consloe commands to spawn him will make him hostile)

Another scientist can be found outside Vault 87. This female scientist was probably killed by the huge amount of radiation which lingers outside the Vault entrance.
