Principles Of Radiation Protection

Introduction Ionizing radiation is radiation with enough kinetic energy so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized. Such an event can alter chemical bonds and produce ions, that are especially …
