<p>A methods for inspecting a cargo space of a truck in which the truck is moved past an X-ray source that is switched on while the cargo space is being moved past the source and is switched off while the driver's cab is being moved past the source. The truck is irradiated on one side with electromagnetic radiation, particularly laser beams, having a wavelength between 200 nm and 3000 nm, and the radiation reflected at the transition between the driver's cab and the cargo space is measured in order to determine the switch-on time for the X-ray source.</p> |
