The first part of the book deals with the production, characteristics, and interactions of ionizing radiation used in medical imaging. Ionizing radiation is radiation that has enough energy to ionize atoms or molecules, which means to remove one or more electrons from them. Ionizing radiation can be classified into two types: photons and charged particles. Photons are electromagnetic waves or particles that have no charge or mass, such as x-rays and gamma rays. Charged particles are particles that have either a positive or negative charge, such as electrons, protons, alpha particles, beta particles, etc.
