1. INTRODUCTION In X-ray diagnostics, radiation that is partly transmitted through and partly absorbed in the irradiated object is utilised. An X-ray image shows the variations in transmission caused by structures in the object of varying thickness, density or atomic composition.

Introduction X-ray diffraction can be used to determine a materials crystalline structure and lattice parameter. This information can then be used to identify the material being analyzed since each metallic element in the periodic table has a unique combination of lattice structure and parameter at room temperature.. X rays are produced in a more energetic version of the same process. If you want to make X rays, you simply fire a beam of really high-energy electrons (accelerated using a high-voltage electricity supply) at a piece of metal (typically tungsten). What gets reflected back, in this case, is neither light nor electrons but a beam of X rays Introduction: X-Ray Diffraction 1 • XRD is a powerful experimental technique used to determine the - crystal structure and its lattice parameters (a,b,c,a,b,g) and - spacing between lattice planes (hkl Miller indices) this interplanar spacing (d hkl) is the distance between parallel planes of atoms or ions

An Introduction to X-ray Powder Diffraction Analysis. When a beam of X-rays illuminates a single crystal, many spots are generated. The positions of the spots are determined by the size and shape of the unit cell and the symmetry. The intensities of the spots are determined by the arrangement of the atoms within the crystal Of these radioactive sources X-rays and gamma rays are in general practice used in industrial radiography. Gamma rays have greater penetrating power than X-rays. X-rays have a smoothly spread, continuous spectrum, while gamma rays have a discrete spectrum characteristic to the particular radioactive element involved. 1.2 X-ray Generator Hospital staff have a duty to use X-rays responsibly Having a basic knowledge of radiation physics and safety is helpful in appreciating some of the limitations of X-ray investigations. The science of radiographics deal with understanding and overcoming some of these difficulties The x-rays rube is essential to the machine as it is the piece that ultimately produces X-rays. The high-voltage power supply uses a transformer to accurately alternate between the voltage of currents being sent to the emitter or to the anode

In X-ray imaging, each quanta carries much more energy hν = hc/λ than in visible light, so there are many fewer quanta, and these quanta are the main source of variability between experiments. Noise is most meaningfulif it is put in perspectiveby comparingto signal strength. In X-ray radiography,the relevant comparison is to contrast. Artifact -- In neutron scattering, scattering nuclei are point particles whereas in x-ray scattering, atoms have sizes comparable to the wavelength of the probing radiation. In the very wide angle (diffraction) range, x-ray scattering contains scattering from the electron cloud, whereas neutron scattering does not. In the SANS range, this is not the case X-ray fluorescence spectrometry has been an established, widely practiced method of instrumental chemical analysis for about 30 years.
