Abstract
An X-ray beam flattener of predetermined symmetrical shape for attenuating the radiation intensity of the beam in decreasing amounts as the angle from the central axis increases. The symmetrical shape is made from a low Z, high density material such as Al.sub.2 O.sub.3 BeO, BeAl.sub.2 O.sub.4, B.sub.4 C or SiC. A further thin layer of high Z material may be coated on the forward end of the symmetrical shape to absorb low energy photons.
