A method, device and retrofitting kit is disclosed that will protect materials that are housed within a storage device from one or more forms of radiographic imaging. A target subject is at least partially covered with a first and second layer of radiographic cloaking material. The first layer of radiographic cloaking material is configured to defeat a first type of radiographic beam, such as a photon beam. The second layer of radiographic cloaking material is configured to defeat a second type of radiographic beam, such as a particle beam.
