Radiation Biology. Definitions. Radiation is a process in which energetic particles or energetic waves travel through vacuum or media. Radiobiology (also known as radiation biology) is the study of the action of ionizing radiation on living things. History.
Radiation Biology . Reading: Chapter 4. Radiation Biology. Radiation Biology is the study of the effects of radiation on living tissue . X -rays are a form of ionizing radiation . When x-rays strike patient tissues, ionization results.

Radiation Biology. Particles lose energy in matter. Eventually energy loss is due to ionization. Energy transferred describes the kinetic energy gained by charged particles. Energy imparted is the energy lost by charged particles. Energy Transfer. 1.1. 2.8. 4.2. 5.4. 10 MeV.
Radiation Biology. Chapter 5: Overview of Cell Biology Laura herz , BA, RT (R). The Cell. Cell is the fundamental component of structure, development, growth, and life processes in the body Body is composed of trillions of cells Some are freely moving, independent units
