Radiation Damage
Radiation is one of the 8 damage types and is essential for capturing ships using the Remote Control skill. Radiation weapons, like the Neutron Laser, are usually beam weapons. However, tracking projectile radiation weapons do exist.
This type of damage won't actually destroy a ship. If the final "kill" shot delivered to a ship is with radiation it renders the ship's crew inert, and the ship is ready to be captured with a Prismatic Conversion weapon (abbreviated PC).
Radiation can also facilitate the capturing of a base in the same way as a ship, with the exception that a PC is not necessary.
While many classes use this type of damage, the Fleet Commander class is the most notable, stemming from the large damage bonuses given by the Radiation Expert to Radiation Weapons.
