Radiation Information Network's Radiation Related Terms Basic Terms Radiation Radiation is energy in transit in the form of high speed particles and electromagnetic waves. We encounter electromagnetic waves every day. They make up our visible light, radio and television waves, ultra violet (UV), and microwaves and are part of a large spectrum of energies. These examples of electromagnetic waves do not cause ionizations of atoms they interact with because they do not carry enough energy to remove electrons from atoms. Radiation can be ionizing or non-ionizing. Ionizing radiation Ionizing radiation is radiation with enough energy so that during an interaction with an atom, it can remove tightly bound electrons from their orbits, causing the atom to become charged or ionized. Examples are gamma rays and neutrons. Non-ionizing radiation Non-ionizing radiation is radiation without enough energy to remove tightly bound electrons from their orbits around atoms. Examples are microwaves and visible light. Health Physics Health Physics is an interdisciplinary science and its application, for the radiation protection of humans and the environment. Health Physics combines the elements of physics, biology, chemistry, statistics and electronic instrumentation to provide information that can be used to protect individuals from the effects of radiation. For more on Health Physics, visit the career section of the Health Physics Society or the EPA career website. Radioactivity Radioactivity is the spontaneous transformation of an unstable atom and often results in the emission of radiation. This process is referred to as a transformation, a decay or a disintegrations of an atom. Radioactive Material Radioactive Material is any material that contains radioactive atoms. Radioactive Contamination Radioactive contamination is radioactive material distributed over some area, equipment or person. It tends to be unwanted in the location where it is, and has to be cleaned up or decontaminated.
