The present invention concerns a device for the decontamination of hollow objects (7) with a cavity (20) such as caps, comprising: (i) first exposure means (4) comprising at least an UV radiation source (5) and a reflector (6) oriented toward the cavity (20) of the positioned objects (7), able to produce a direct exposure to UV radiations of surfaces inside said cavity (20), (ii) second exposure means (1) comprising at least an UV radiation source (2) placed on the opposite side relative to the cavity (20) of said positioned objects (7), said second exposure means (1) being able to expose surfaces inside the objects cavity (20) to UV radiations by diffusion and/or transmission of UV radiations through the walls (21) surrounding said objects cavity (20), and said first and second exposure means (4, 1) cooperating for producing a global exposure to UV radiations of the surfaces inside said objects cavity (20). The present invention concerns a method for the decontamination of hollow objects.
