Plasma Grenade (Fallout 3)

The Plasma Grenade is a weapon in Fallout 3.

Characteristics
The Plasma Grenade is a magnetically-sealed plasma delivery unit, with detonating explosives, creating a fiery blast of green superheated plasma on detonation, with a high chance to cripple limbs. A critical hit will reduce the target to green goo. It seems to have the same blast radius as its less powerful variant, the Frag Grenade.

It is also possible to plant a live grenade on an NPC by passing one from your inventory to the NPC's inventory via pickpocketing. This will kill the NPC, regardless of how much health he has, but far more common grenades such as the Frag Grenade can do this too.

Though one might be led to believe so, Plasma Grenades are not affected by your ranks in Energy Weapons, but rather your Explosives rank. Taking ranks in the Demolitions Expert perk will further improve the damage inflicted by any grenades in your possession, up to an additional 60% damage.
