1. A nonintrusive inspection method for the scanning of vehicles using radiations, comprising the following stages:

  • the vehicle is placed in a marked spot, having access in the exclusion area through an automated traffic management subsystem that automatically commands the functioning of the barriers and of the entry/exit semaphores;

    the protection of the exclusion area is activated after the driver of the vehicle that is to be scanned left the exclusion area;

    the scanning process is initiated by remote commands to the mobile scanning unit and the source carrier robot;

    the radiation source is activated;

    the slow and constant motion movement of the two mobile units is started, these units moving rectilinear and uniform on parallel trajectories framing the scanned vehicle, the source robot moving synchronized with the mobile scanning unit;

    the movement of the mobile units is automatically controlled by electronic and informatics modules, connected with the control centre in a local area network, through radio modems, centre from which they receive commands, and towards which they send in real time status information and dedicated data;

    the stopping of the scan is performed automatically in the following situations, when the detector boom has passed the extremity of the scanned vehicle and the detectors receive the maximum level of radiation, at the end of the programmed scan length, when the protection limiter of the movement is triggered, when the protection of the exclusion area has been breached, when the proximity sensor has been triggered indicating dangerous distance between the detector boom and the scanned vehicle, when obstacles close to the guiding paths have been automatically detected by sensors placed on the mobile units;

    the image resulted from scanning the vehicle is displayed on the operator'"'"'s monitor;

    at the end of the stage the protection of the exclusion area is automatically deactivated, and the vehicle may leave the scanning area;

    the two mobile units move back to the start position and the scanning cycle may be restarted.
