A device is provided for the decontamination of hollow objects with a cavity such as caps, including: (i) a first exposure apparatus including at least a UV radiation source and a reflector oriented toward the cavity of the positioned objects, able to produce a direct exposure to UV radiations of surfaces inside the cavity, (ii) a second exposure apparatus including at least a UV radiation source placed on the opposite side relative to the cavity of the positioned objects, the second exposure apparatus being able to expose surfaces inside the objects cavity to UV radiations by diffusion and/or transmission of UV radiations through the walls surrounding the objects cavity, and the first and second exposure apparatus cooperating for producing a global exposure to UV radiations of the surfaces inside the objects cavity. A method is also provided for the decontamination of hollow objects.
