Method and apparatus for wide angle beam scanning to internally irradiate hollow objects with a beam of charged particles utilizes a scanning deflection device to scan the beam within the object to be irradiated through an angle of deflection greater than 90 DEG from the axis along which the beam is received by the scanning deflection device. The object to be irradiated can be rotated about the scanning deflection device or the scanning deflection device can be rotated to circumferentially irradiate the object, and the object is translated relative to the scanning deflection device to irradiate an entire object, such as a tube, a container having a closed end or an object having a toroidal configuration, such as a pneumatic tire.
