32.1 Biological Effects of Ionizing Radiation Ionizing radiation consists of photons and/or moving particles that have sufficient energy to knock and electron out of an atom or molecule, thus forming an ion. Exposure is a measure of the ionizing radiation produced in air by X-rays or γ-rays. In passing through the air, the beam produces positive ions whose total charge is q . Exposure is the charge per unit mass of the air. m q × = - 4 10 58 . 2 1 roentgens) (in Exposure

32.1 Biological Effects of Ionizing Radiation For biological purposes, the absorbed dose is a more suitable quantity because it is the energy absorbed from the radiation per unit mass of the absorbing material: material absorbing of Mass absorbed Energy dose Absorbed = kg J 1 Gy 1 = gray gray 01 . 0 rad 1 =
