ABSTRACT:
The present invention refers to a device for electron beam irradiation of at least a first side of a web, the device comprising a tunnel through which the web is adapted to pass, said tunnel being provided with a web inlet portion, a web outlet portion and a central portion adapted to receive at least a first electron beam emitter provided with an electron exit window through which electrons are adapted to be emitted into the tunnel. The tunnel is being angled at least two locations in each of the inlet portion and the outlet portion in such a way that any X-ray formed during the electron beam irradiation of the web is forced to hit the tunnel wall at least twice before exiting the tunnel.
