A detector enclosure is provided with a window opening in the detector enclosure. A reference body having an image slit is accessible from within the detector enclosure, and a radiation detector is used to alternately receive radiation through the window opening in the detector and from the reference body through the image slit. An indication of the two received radiation levels or a difference between the received radiation levels is used to provide an indication of a change in the closed status of the enclosure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radiometric cargo security device","description":"Detection of a breach in security of an enclosure, such as a shipping enclosure, is indicated by detection of a change in a closed status.
