Radtrooper
the shortened term used to describe stormtroopers who were specially trained and equipped for operations in radiation zones. The armor of the radtrooper was based on the armor used by standard stormtroopers, but was impregnated with a lead-polymer substrate that allowed the radtrooper to operate for extended periods in lethal radiation zones. Radtroopers were most often used when the Empire needed to subjugate a planet quickly. Using atomic weapons or neutron bombing runs, any armed resistance on the planet was quickly eliminated. The radtroopers were dispatched almost immediately into the warzones, to mop up any surviving resistance on the ground.
