X-rays ( X-radiation) are a form of high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 [ 1] and named it X-radiation to signify an unknown type of radiation.
An X-ray spectrograph consists of a high voltage power supply (50 kV or 100 kV), a broad band X-ray tube, usually with a tungsten anode and a beryllium window, a specimen holder, an analyzing crystal, a goniometer, and an X-ray detector device. These are arranged as shown in Fig. 1. Fig. 1.
A powder X-ray diffractometer in motion. X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer ...
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical ("diagnostic" radiography and "therapeutic") and industrial radiography. Similar techniques are used in airport security, (where "body scanners ...
Natural X-ray sources: Astrophysical X-ray source, as viewed in X-ray astronomy. X-ray background. Naturally occurring radionuclides. Artificial X-ray sources. Radiopharmaceuticals in radiopharmacology. Radioactive tracer. Brachytherapy. X-ray tube, a vacuum tube that produces X-rays when current flows through it.
X-Ray Records [1] is an imprint under the Cleopatra Records, Inc. label group that focuses on hip hop and modern R&B. The imprint began in 2000 just as the label was starting to diversify after predominantly focusing on gothic and industrial music throughout the late ‘90s. It made an auspicious start with SX-10, [2] the hip hop/metal hybrid ...
An X-ray microscope uses electromagnetic radiation in the X-ray band to produce magnified images of objects. Since X-rays penetrate most objects, there is no need to specially prepare them for X-ray microscopy observations. Unlike visible light, X-rays do not reflect or refract easily and are invisible to the human eye.
Industrial radiography is a modality of non-destructive testing that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures. It plays an important role in the science and technology needed ...
