ABSTRACT:
An irradiation device for the uniform irradiation of goods by means of electro-magnetic radiation having a quantum energy larger than 5 KeV comprises at least one radiation source, means for the reception of goods to be irradiated, and at least one shielding element arranged laterally of the radiation path from the radiation source and the center axis of the goods in such a manner that the shielding effect of the shielding element increases with increasing lateral space from this radiation path. The radiation source, the shielding element and the means for the reception of the goods to be irradiated are arranged to allow for the radiation to enter the goods through the entire superficies thereof in such a way that the region immediately around the center axis of the goods is irradiated without radiation being affected by the shielding element.
