Radiation - ANS energy in transit from one location to another; a transfer of energy that results from either a change occurring naturally within an atom or a process caused by the interaction of a particle with an atom Ionizing Radiation - ANS radiation that produces positively and negatively charged particles (ions) when passing through matter Attenuation - ANS any process that decreases the intensity of the primary photon beam directed toward some destination; total reduction i...
