WebThe number of x-ray photons produced is determined by the current (amps) through the x-ray tube. X-ray spectrum When electrons hit the anode, the energy is absorbed. 95% is dissipated as heat, but the remaining 5% produces x-rays from the anode material. The material from which the anode is made will determine the spectrum, or distribution, of ... WebIn a Geiger-Müller tube, or Geiger counter, incoming X-ray photons ionize atoms in a gas-filled volume. An applied high voltage induces further ionizations from collisions between liberated electrons and neutral atoms, creating an avalanche of charged particles and a large electrical pulse that is easily detected.
