Electromagnetic radiation or atomic particles capable of displacing electrons from around atoms or molecules, thereby producing charged atoms or molecules or ions. The more common types of ionizing radiation are x-rays, gamma rays, alpha particles, and beta particles. Ionizing radiation are extremely harmful to all living beings. The ionosphere and stratosphere protect living beings from the ionizing radiation that arrives from the sun and other celestial bodies.
Radiation with enough energy to remove one or more electrons from atoms it encounters, creating ions inside living cells. (An ion is an atom that carries a positive or negative electrical charge.) Ionizing radiation leaves positively charged particles such as alpha and beta, and non-particulate forms such as X-rays and gamma radiation. These ions can damage key substances in cells, including the DNA. Such damage can lead to cancer or other defects.

Any type of radiation which, directly or indirectly, can change the electric charges of atoms or molecules. It is produced when radionuclides decay.
Radiation of high enough energy to cause ionization. The energy of a photon of electromagnetic radiation or nuclear radiation is given to an orbital electron. If it is sufficiently high enough to promote the electron out of the influence of its nucleus, it is ionizing radiation and an ion will be formed. sotope An element can exist in several different isotopes. Each isotope of an element has the same proton number but a different number of neutrons, making the nucleon number different. All isotopes of an element have the same chemical properties (the way they react with other substances) but different physical properties (boiling point, melting point, density etc.). Some isotopes are more common than others but there is no such thing as a 'normal' isotope. The nucleus of some isotopes is unstable, such isotopes are termed radioisotopes.
radiation which has enough energy to produce ions by knocking electrons off some of the atoms it strikes.
Particulate or electromagnetic radiation which has sufficient energy to remove electrons from the atoms of material with which it interacts. Ionizing radiation may be emitted from radioactive materials or from radiation-producing machines. The most important forms of ionizing radiation include alpha particles, beta particles, neutrons, gamma rays, and X-rays.
Any of the various forms of radiant energy that causes ionization when it interacts with matter. The most common types are alpha radiation, made up of helium nuclei; beta radiation, made up of electrons; and gamma and x radiation, consisting of high-energy particles of light (photons).
Ionizing radiation is radiation with a very high level of energy. It has so much energy that when it interacts with an atom, the energy can remove electrons from their orbits. This causes the atom to become charged or ionized. An example of radiation with enough energy to form ions is x-rays. Other types of energy, like visible light, radio and television waves, ultra violet (UV) and microwaves do not cause ionization of atoms because they do not carry enough energy to separate molecules or remove electrons from atoms.
Radiation commonly associated with X-Ray or other high energy electromagnetic radiation which will cause DNA damage with no direct, immediate thermal effect. Contrasts with non-ionizing radiation of lasers.
Radiation, such as that found in cosmic rays, causes atoms in the material through which it passes to lose electrons. The electrons are pulled away from the atoms by the strong attractive force between the positively charged proton (or heavy ion) and the orbital electron. Ionizing radiation can kill cells outright, damage their genetic material, and, in some instances, induce cancer.

The type of radiation capable of removing one or more electrons from any atom(s) it encounters, leaving positively charged particles such as alpha and beta. When alpha and/or beta particles strike the human/canine body the particles change the existing atoms. The change occurs because the covalent bond is broken, meaning the molecule that suffers an ionization is so badly damaged it loses its normal function.
