A monochromatic X-ray radiation source includes an anode for producing X-ray radiation, a target enclosed by the anode for converting X-ray radiation into fluorescence radiation and a screen located between the target and the anode for screen the target from electrons. A higher output of fluorescence radiation is attained in that the screen comprises an element having an atomic number greater than 50, for example, tungsten or tantalum.
