ionising radiation acts on tissue depending upon :

onizing Radiation-radioactivity measurements it has linear radiating energy High energy paicles and photons that ionise atoms and molecules along their tracks in a medium are called ionizing radiation. For example, a, {3, y, cosmic rays and X-rays are ionizing radiation. Most radioactive measurement are based on their ionizing effect. Ionizing radiation causes illness such as cancer and death. Radiation effect is a health and safety concern. Ionizing radiation can also be used in industry for various purposes. Light and microwaves that do not ionize atoms and molecules are called non-ionizing radiation. Ionizing Radiation . ref : david sutton 9th ed
