All TIRs which make entrances and exits from the country are being screened into the smallest detail without making any physical search by means of x rays thanks to X-Ray Devices. The materials that are present in TIRs, which are put subject to screening, are being examined by educated operators after they passed image processing; and the materials can be distinguished organically and inorganically. Thus, goods which were placed in secret parts of the vehicle such as gold, historical artefacts, drugs, guns etc. can be detected easily. On the occasion of detecting sensitive items, physical examination of TIRs related part is enabled.
