A method and system for scanning a beam of charged particles to control radiation dose distributions is implemented by deflecting the beam through a plurality of positions across a conveyor path along which an object to be irradiated is moved, and controlling the length of time the beam remains at each position in accordance with the radiation dose required at each position. The beam may be deflected by a single magnet beam scanning device supplied with a drive signal having a steplike waveform or by a series of sequentially operated, controllable deflection magnets arranged along a beam pipe to sequentially deflect the beam toward the object to be irradiated from different positions.
