![]() The maximum photon energy, therefore, in. KV establishes the energy of the electrons as they reach the anode, and no x- ray photon can be created with an energy greater than that of the electrons. Gamma and X-Ray Detection Figure 1.1 Efficiency Calibration DETECTOR OVERVIEW The kinds of detectors commonly used can be categorized as: a. Radiology and medical imaging tutorials for UK medical students. ![]() What is electromagnetic radiation? The electromagnetic spectrum is a map of all the types of light that we can identify. This makes it a type of ionizing radiation, and therefore harmful to living tissue. X-ray photons carry enough energy to ionize atoms and disrupt molecular bonds. Folie.1 © 2001 Bruker AXS All Rights Reserved Introduction to Powder X-Ray Diffraction History Basic Principles. Characteristic x-rays are emitted from heavy elements when their electrons make transitions between the lower atomic energy levels. Detection of Diffracted X-rays by Photographic film A sample of some hundreds of crystals (i.e.
