بیشترCaesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium.
بیشترRadiographic imaging equipment. x Rays are produced by bombarding a metal target by high energy electrons. In conventional radiography, x rays passed through the human body are absorbed, which causes attenuation of the incident beam. The uniform x ray beam emitted from the source is modulated as it passes through the human body and these changes are recorded on the film.
