The portable x-ray fluorometry device which possesses the absorption color where the taper is attached

摘要

Topic A leak of the x-ray from the hand-held x-ray fluorometry device is prevented.SolutionsThis invention being the measurement equipment in order to measure the constitution of the element of the test material, the transmitted emission radiation source in order to irradiate the suffering lighting territory of the test material the fluorescent radiation by the test material and detects, the detector and the detection signal in order to generate the detection signal, platen of the attenuation material which features the controller in order to convert to the spectrum which decides the feature of constitution of the test material and that, with radial distance from the suffering lighting territory of parallel direction thickness decreases to the surface of the test material substantially and, has. As it adjoins to the suffering lighting surface of the test material, from this lighting surface extends outside, in order to surround this surface, platen of the attenuation material has extended. With specified execution form, as radial distance from the central suffering lighting territory of the test material increases, in order for thickness of attenuation platen to become thin, the taper is attached to attenuation platen.
