Abstract: Device for irradiation of at least one article/product by means of beams, especially by means of high-energy electron beams which can be produced in an irradiation system, the beams emerging from the electron accelerator in a radiation area, comprises at least one scanner means (54) which defines the radiation area (56), the radiation area (56) being formed spaced apart from the scanner means (54) in at least one plane (En) in which there is at least one transport means (TEn), and by means of which at least one bar-shaped/pipe-shaped article (Gr) and/or other articles (Gn) can be moved into the irradiation position.
