Abstract

In a device and processes for inspecting an object (1), particularly a piece of luggage, in which radiation is emitted by a stationary radiation source (2) while the object (1) is transported in a straight line through the radiation with intensity levels of unabsorbed radiation being detected by a detector arrangement (3) and processed into an image of the object (1), the object (1) is rotated by a rotating device (8) through an angle after a pass through the radiation in order to change its transport position, and is subsequently transported through the radiation again with another image being produced. This facilitates improved inspection by reducing so-called “dark alarms.”
