Energy weapons project their energy in a specific direction. There would be minor leakage of the radiation once it left the shielded barrel, however that energy is traveling at the speed of light away from the ship, so exposure should be negligible at best. A ship or crew would be exposed to far more incoming radiation from weapons. Plus the ships operate in space and basic radiation protection is the norm. Ergo, unless your weapon is misfiring or I'll-maintained gun crews should receive no exposure. The exception could be if the beam is traveling the length of the ship, though unless it has lost its focus that, too, would be negligible. If the energy stream is already degrading that much from the time of firing its range would be severely limited.
And fusuon/plasma weapons would have to utuilzie some sort of containment process in order to strike a vessel at any distance of more than a few hundred meters. Otherwise firing plasma would dissipate rapidly like a flamethrower.
