Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent posttransition metal and one of the pnictogens with chemical properties resembling its lighter homologs arsenic and antimony. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86
Multiferroic bismuth manganite BiMnO 3 is known as a material that exhibits both ferromagnetic and ferroelectric properties making it interesting for various technologicalely, preparation of BiMnO 3 is not possible by a conventional solidstate reaction and it can form only from mixture of oxides at high pressures 40 kbar.
Xray. Fundamentally the same as gamma rays, but originating from electrons outside high atomic number elements, such as tungsten, lead and bismuth. Compton scattering. The transfer of part of the energy of a gamma ray photon to an High density makes tungsten ideal for applications where powder is dispersed in a polymer. Good activation

Bismuth iron garnet Bi 3Fe 5O 12 thin lms, for use in magnetic optics, were prepared by a pulsed laser deposition method using Bi and Fe mixed powder targets in oxygen gas. The deposition rate of the lm strongly depended on the target mixture. The Xray diffraction and Xray
This element distribution was confirmed using energy dispersive Xray EDX mapping. Figure 4 shows the threehour asmilled powder with bismuth, tantalum, and oxygen mappings, where corresponding elements are uniformly distributed within the examined area,
Definition. Powder Xray Diffraction XRD is one of the primary techniques used by mineralogists and solid state chemists to examine the physicochemical makeup of unknown solids. This data is represented in a collection of singlephase Xray powder diffraction patterns for the three most intense D values in the form of tables of interplanar spacings D, relative intensities II o, and

Collimators Collimation XRay Collimators A collimator is a device that limits the radiation output of an Xray source. Without a collimator, Xrays would escape which would flood the detector with radiation and prevent a clear image from being attained. An Xray collimator can be made from multiple materials including lead, tungsten, molybdenum, tin, bismuth, Collimators Collimation
Radiation Sources and Attenuation Mechanisms Several common sources of xray and gamma radiation are listed in table 2. When selecting the best shielding material for a particular source of radiation, it is important to understand the
