Web9 de ago. de 2016 · Since only a small fraction of about 1 % of the energy generated in an X-ray tube is actually emitted as X-rays and the rest of the energy is released as heat, the temperature of the anode target can be very high during the operation of the X-ray tube. Therefore, the anode has to be made of high-temperature materials.

WebX-rays are produced by interposing a metal target between the electron beam and the product to be treated. X-rays are more penetrating than electron beam, but less penetrating than gamma rays. They are more costly than gamma processes but will decrease exposure times, require less shielding and shorten turnaround times. WebX-ray emission is sometimes a by-product of a nuclear transformation.In the process of electron capture, an inner-shell atomic electron is captured by the atomic nucleus, initiating the transformation of a nuclear proton into a neutron and lowering the atomic number by one unit (see radioactivity: Types of radioactivity).The vacant inner-shell orbit is then quickly …
