The Catalyst

 The mechanism of  heat loss  in the modern X-ray tube is  radiation. The atomic number of tungsten is  74. X-ray film is coated with a photosensitive emulsion on both sides. The active is  silver bromide  and  silver iodide. In routine films, both sides are coated, whereas, in mammography, only one side of the film is coated. X-ray films are most sensitive to blue light and least sensitive to red light. So, the  safe  light used in the darkroom is a  red light. X-rays are produced when the electron beam  decelerates close to the nucleus  of the atom in the anode. The production of X-rays is as follows: Current is passed through a tungsten filament which acts as the cathode 🠗 Electrons are emitted as a result of thermionic emission 🠗 Electrons bombard the target anode, a tungsten disc 🠗 Results in the conversion of energy into heat (99%) and X-ray photons(1%) The target anode is made of a tungsten disc in ordinary diagn...
