The invention relates to a simulation chamber for setting of explosive charges contained in freight in a controlled manner under simulated conditions, comprising a closed explosion chamber (1), into which the freight (2) is introduced and in which real-time conditions are specified that match ambient conditions of the freight (2) on an intended transport path. In order to further develop such a simulation chamber in such a way that even explosive charges that cannot be detected by means of the hitherto existing examination and testing methods can be recognized, a mobile radio testing unit (4) is provided according to the invention, by means of which a mobile radio device contained in the freight (2) can be detected.
