, 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
K
directed toward some destination; total reduction in the number of x-rays remaining in a beam
after penetration through a given thickness of tissue
C
Absorption - ANS transference of energy from an x-ray beam to the atoms or molecules of the
matter through which it passes
