X Ray Fluorescence (XRF) SERC

The analysis of major and trace elements in geological materials by x ray fluorescence is made possible by the behavior of atoms when they interact with radiation. When materials are excited with high energy, short wavelength radiation (e.g., X rays), they can become ionized.

X ray fluorescence

X ray fluorescence

X ray fluorescence is the emission of characteristic quot;secondaryquot; X rays from a material that has been excited by bombarding with high energy X rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects

XRF (X ray fluorescence) is a non destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X ray emitted from a sample when it is excited by a primary X ray source.

We have suggested the use of x ray fluorescence analysis as an alternative method of cadmium detection in vivo (Ahlgren et a1 1980a), using it in the same way as for in vivo analysis of lead (Ahlgren eta1 l976,1980b, Ahlgren and Mattsson 1979).

Energy dispersive X ray fluorescence (EDXRF) is a method of detecting metals and other elements, such as arsenic, selenium, bromine, and iodine, in soil and sediment. Some of the primary elements of environmental concern that EDXRF can identify are arsenic, barium, cadmium, chromium, copper, lead, mercury, selenium, silver, and zinc.

The most common element determined in this application is lead (Pb), but the unit is also capable of detecting mercury (Hg), cadmium (Cd), selenium (Se) and many others. Handheld XRF has also become very popular in analysis of Art and Archeological artifacts as well as for research into analysis of almost any sample.

X Ray Fluorescence (XRF) and Neutron Activation Analysis (NAA) X ray fluorescence (XRF) and neutron activation analysis (NAA) are the two main methods for noninvasive in vivo determination of heavy metal concentrations in humans. Various XRF techniques have been developed for the measurement of cadmium, mercury, and lead, primarily in occupationally exposed persons to evaluate whether these
