http://dbpedia.org/ontology/abstract X-rays are produced when electrons are accX-rays are produced when electrons are accelerated or decelerated. (This is why young children are warned to keep their distance from old televisions). Tungsten is a good source for producing this kind of radiation due to its high atomic number and high melting point. The high-energy electrons formed in the cathode side of an X-ray tube can interact with the electrons of a tungsten target on the anode side and produce ionized radiation or white radiation. When an electron is attracted toward the energy of the tungsten nucleus, the electron will either slow down, losing some of its energy and deviate from its original path (bremsstrahlung) or knock out and replace an existing electron orbiting the nucleus (characteristic radiation). The energy difference that is lost when the electron slows down in the first reaction or the difference in energy between the original electron and the one replacing it in the second reaction is released as an X-ray photon. This radiation is referred to as ionized or white radiation. The voltage applied across the X-ray tube establishes the kinetic energy of the electrons when they strike the target. When voltage is applied, the temperature of the cathode establishes the rate of electron emission (current). The temperature of the filament is controlled by adjusting the voltage applied across the filament (the current passed through the filament).(the current passed through the filament).
