Radiation biology is the study of the effects of ionizing radiation on biological tissues and living organisms. It combines radiation physics and biology. The purpose of this chapter is to introduce the terminology and basic concepts of radiobiology to create a...
24 Σεπ 2023 · This chapter firstly describes the different types of radiation, the sources, and the radiation interactions with matter. The basic concepts of radioactivity and its applications are also...
future radiation protection personnel should have a basic understanding of the biological and clinical basis to the exposure limitations that they are subject to and that they implement for industrial workers and the public at large.
The second presents the biology necessary for understanding how radiation affects cells and the mechanisms of radiation injury and repair. The third section describes the methods used to identify and measure the risks to persons who are exposed to radiation.
4 Basic Principles of Radiation Biology. To understand how ionizing radiation can damage biologic systems, it is necessary to understand what ionizing radiation is and how it interacts with tissues in the body.
Ionizing radiation consists of particles and photons that have sufficient energy to ionize atoms in the human body, thus inducing chemical changes that may be biologically important for the functioning of cells. The greatest exposure to ionizing radiation is from natural sources.
