| Zusammenfassung | After the security related occurrences in the past few years, there is an increasing need for airport security and border controls. In the combat against terror and smug-gling, X-rays are used for screening of persons and vehicles. The exposure of humans with ionising radiation arises the question of justification for this, reliable and traceable dose values are needed. A research project of the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety was initiated with the scope of measuring the ambient dose equivalent, H*(10), and the personal dose equivalent, Hp(10), for typical types of personnel and vehicle X-ray scanners, using the transmission and/or backscatter method. The measuring quantities to use for these investigations are discussed and the measuring instruments are presented, the experimental set-up is described. For the personnel X-ray scanners investigated. The obtained dose values are in the range from 0.07 μsV to 6 μsV. these values are compared to the dose values of the natural environmental radiation and some medical exposures. |
