ABSTRACT:
A radiation measuring arrangement is present which comprises a radiation source producing a radiation beam penetrating the radiography subject, and also a radiation receiver which determines the radiation intensity behind the subject. The measuring arrangement is arranged on a support which can be displaced parallel to the plane of the layer on a rotating track. A motor for driving the rotating track is also coupled with a gear ring, rotatably mounted on the rotating track so that this ring is continually rotated, while the rotating track is driven from the motor via a step by step drive unit. A gear wheel (14) is driven by the ring and in turn drives a crank for effecting displacement of the support for the measuring arrangement and also drives a further crank for a weight equalizer member. The lever arms of the cranks may be adjusted by a common motor from a remote station.
