Nuclear Physicist/Fallout 4

Nuclear Physicist is a perk in Fallout 4.

Effects

 * With the first rank of this perk, radiation weapons deal 50% more damage, and fusion cores last 25% longer. The second rank raises the bonus damage for radiation weapons to 100%, and fusion cores last 50% longer. The third rank allows fusion cores to be ejected like devastating grenades and they last twice as long.
 * To use the fusion core grenade effect (which explodes like a Mini Nuke), the player has to equip a non-melee weapon and hold the grenade button. The fusion core will drop out of the back of the Power Armor suit, and start a grenade countdown.
 * The extra fusion core duration effect applies to Gatling lasers: The Gatling will receive the full 500 units of power, but when expended, the fusion core is not remved, but placed back into the inventory with a 25% or 50% charge.
