ABSTRACT:
A body is irradiated by a primary radiation beam; the scattered radiation produced thereby is incident on a detector device consisting of a plurality of detectors and is a measure for the density distribution of materials in the primary beam. However, this gives rise to multiple scattered radiation which disturbs the measurement. The present invention provides a device in which disturbance by multiple scattered radiation is greatly reduced, without any significant effect on the scattered radiation originating from the primary beam. A device in accordance with the invention is provided with flat laminations which are arranged between the primary beam and the detector device and which are aligned with the primary beam in a fan of flat planes.
