X-ray Fluorescence Holography: Principles, Apparatus, and Applications

Development and Application of Laboratory X-ray Fluorescence Holography Equipment

The X-ray fluorescence holography (XFH) method has drawn the attention of many researchers as a novel experimental technique for imaging a three-dimensional local atomic structure around a certain element in a single crystal. Synchrotron radiation (SR) has been mainly used for the measurements because of extremely weak signals which are about 0.3 % of isotropic fluorescent radiation. The measur...

Dosimetry of Occupational Radiation around Panoramic X-ray Apparatus

Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...

Quantum Electrodynamics of Internal Source X-Ray Holographies: Bremsstrahlung, Fluorescence, and Multiple Energy X-Ray Holography

Quantum electrodynamics (qed) is used to derive the differential cross sections measured in the three new experimental internal source ensemble xray holographies: bremsstrahlung (BXH), fluorescence (XFH), and multipleenergy (MEXH) x-ray holography. The polarization dependence of the BXH cross section is also obtained. For BXH, we study analytically and numerically the possible effects of the vi...

X-Ray Fluorescence Microtomography in Biological Applications

Forensic applications of X-ray fluorescence microscopy

The development of highly efficient X-ray optics has allowed the development of bench-top XRF systems which have high intensity X-ray beams with diameters ranging from 10 micrometres through to a few millimetres. Coupled with integrated high magnification optical cameras, these systems are ideally suited to the needs of the forensic scientist. A microscopic particle from a crime scene can be an...
