Abstract

An arrangement and a method for irradiation of products by charged particles. The arrangement comprises a particle acceleration device and a radiation chamber, in which the products are irradiated from at least two sides, by that the particle beam is deflected with a scanning magnet and redeflected with redeflection magnets. The particle beam impinges on the products substantially parallel to the main normals of the surfaces of the products, which normals are positioned substantially perpendicular to the direction that the radiation axis has immediately before the deflection. An absorption means comprising a particle stopper is arranged in the space between the pole pieces of the redeflection magnets. A transport device for double-sided irradiation transports the products, which during transport are fixed to the transport device, through the irradiation arrangement.
