WebSurface analysis technologies such as XRF, X-ray diffraction (XRD), and other spectral analysis technologies measure limited depths and surface areas that may not be representative of the entire amount of material on the belt. With PGNAA, sample errors are reduced, and the high-frequency of analysis helps reduce variation in material quality.

WebX-ray fluorescence, or XRF, is a technique for analysing the different elements of a broad range of materials. They include metals, plastics and minerals. The aim of this piece explain what XRF is, how and why people use it, its advantages and disadvantages, the equipment involved, and look at the kind of data it produces. WebPGNAA uses a strong neutron source (such as Cf-252) to generate a stream of neutrons to bombard the sample material with. This interaction between the neutrons and the sample produces unique prompt gamma rays that are then detected and measured using a high-resolution gamma ray spectrometer. The detector picks up both the energy signatures
