... Negative electrons, surrounding the nucleus, (i.e., orbital electrons) , are present in all uncharged atoms; their number is equal to the number of positive charges (i.e., protons)

From page 205...
... photon, with energy somewhat greater than that of the binding energy of an electron in an atom, transfers all its energy to the electron which is consequently removed from the atom. COMPION SCATlERING: An attenuation process observed for x or gamma radiation in which an incident photon interacts with an orbital electron of an atom to produce a recoil electron and a scattered photon of energy less that the incident photon.

From page 206...
... IONIZATION: The separation of a normally electrically neutral atom or molecule into electrically charged components. IONIZING RADIATION: Electromagnetic or particulate radiation capable of producing charged particles through interactions with matter.

From page 207...
... a quantity that expresses - on a common scale for all ionizing radiations - the biological effectiveness of the absorbed dose. RAD: An older unit of absorbed dose of radiation; 1 red represents the absorption of 100 ergs per gram of absorbing material, such as body tissue.
