Great variety of terrorist means and types of camouflage causes significant difficulties while antiterrorist search activitiesGreat variety of terrorist means and types of camouflage causes significant difficulties while antiterrorist search activities. The same is true regarding covert audio surveillance devices, possibly hidden inside wall constructions, furniture items, other interior objects, gifts and souvenirs. X-ray TV systems are designed to solve the above problems. These devices allow detecting bombs in the ‘lost’ bags, microphones camouflaged in souvenirs and furniture, etc. The X-ray shade image on the display clearly shows the contents of the object. Different corporations offer a wide range of technical facilities and equipment to law enforcement agencies and security service organizations, such as: stationary systems with full biological protection; modular designed multifunctional techniques to accomplish a wide range of search activities, including detection of covert audio/video surveillance equipment located inside concrete walls, etc. Generally, X-ray TV-systems are equipped with micro-focus X-ray generators. In comparison with high-current devices and impulse generators, these devices allow to X-ray any fragment and simultaneously to obtain the image with 4X - 12X amplification, with the same quality. High resolution shadow images allow inspecting thoroughly the contents of packages, wrappers, letters and containers, as well as component parts of electronic devices, in order to detect unauthorized audio/video surveillance devices possibly hidden inside. Besides, these systems allow fine adjustment of the X-ray tube voltage, which is especially convenient to X-ray objects of different thickness and density. This significantly facilitates the inspection of objects of low density, including mail, containing powders, insects and other agents. The portable X-ray TV systems possess the following competitive advantages: § rapid set-up procedures § high running speed § high productivity § high detection ability § no ‘wet’ film development § ability to store the shade images of the X-rayed objects in the database for further use: analyze, processing, etc. § can be powered from rechargeable batteries § low exposure to radiation for personnel and people around To X-ray the objects of high density, special X-ray introscopes may be used. In comparison with standard luminescent displays, these devices enable to convert the X-ray image to visible image with higher efficiency due to the use of the II SUPER Generation electronic optical intensifier.
