Abstract
A collimator for x-ray, gamma, or particle radiation has a plurality of collimator elements made of a tungsten-containing material to reduce scattered radiation. At least one collimator element consists of a tungsten alloy having a tungsten content of 72 to 98 wt.-%, which contains 1 to 14 wt.-% of at least one metal of the group Mo, Ta, Nb and 1 to 14 wt.-% of at least one metal of the group Fe, Ni, Co, Cu. The collimator also has very homogeneous absorption behavior at very thin wall thicknesses of the collimator elements.
