The process by which a neutral atom or molecule acquires or loses an electric charge. The production of ions.
radiation that produces ionisation in matter. Examples are alpha particles, beta particles, gamma rays, X-rays and neutrons
Radiation which integrates with matter to add or to remove electrons from (i.e. to ionise) the atoms of the material absorbing it, producing electrically charged (positive or negative) atoms called ions.
Radiation from radioactive material, X-ray, outer space and even part of the radiation from the sun. Ionising radiation has the ability to split chemical compounds into electrically charged particles (= ions). Some ions may be harmful to cells, but most feared is the effect of ionising radiation on our genetic material (DNA), since this may also be split into ions, thus losing or altering its properties. Small amounts of ionising radiation are harmless, but large amounts or frequently repeated exposure may lead to cancer or birth defects.
Radiation (including alpha particles) capable of breaking chemical bonds, thus causing ionisation of the matter through which it passes and damage to living tissue.
Radiation that produces ionisation in matter. Examples are alpha particles, gamma rays, X-rays and neutrons. When these radiations pass through the tissues of the body, they have sufficient energy to damage DNA.
