When the term “rays” or “radiations” occurs alone in the following paper, it must be understood to mean “X-rays” or “X-radiations.” The term “corpuscular rays” is limited to those corpuscles which have a velocity high enough to allow them to ionise atoms against which they strike. Corpuscles whose velocity is too small to enable them to ionise atoms will be referred to as “δ-rays.” When X-rays pass through matter, energy is absorbed from them and is known to be re-emitted in the following forms:—(1) δ-rays, (2) corpuscular rays, (3) characteristic X-rays, (4) scattered X-rays. Various relations have been found connecting the emission of these forms of energy with the substances in which they originate and with the nature of the X-rays used to produce them.
