Health Physics by Alexander Elliott; Andrew McCormick
Publication Date: 2001-07-05
A range of textbooks and teacher support materials for AS and A level Pre 2008 specification. Health Physics is a title in the Cambridge Advanced Sciences series pre 2008. It has been developed specifically for the new specifications for Advanced Level Physics for teaching from September 2000. Health Physics has been endorsed by OCR for use with the OCR Physics specification A. It provides full coverage of the Physics option module of the same name. In combination with other books in the series it provides full coverage of the Advanced Level specifications. Learning objectives are clearly defined, so that students know exactly what they need to learn. Self-assessment questions (with answers) and exam-style end-of-chapter exercises offer excellent opportunities for independent study. Chapter introductions and summaries provide the basis for structured revision. Student-friendly design make the science accessible to all.
X-rays are a form of electromagnetic radiation, as are radio waves, infrared radiation, visible light, ultraviolet radiation and microwaves. One of the most common and beneficial uses of X-rays is for medical imaging. X-rays are also used in treating cancer and in exploring the cosmos.
X-rays were one of the first forms of biomedical imaging and NIBIB's 60 Seconds of Science explain how they create those images of bones we all know well.
A closer look at a real X-ray tube, and the process of generating X-rays.
This tutorial describes how X-rays are produced and how they interact with the body in forming a radiographic image. X-ray safety issues are briefly discussed.
X-rays are produced due to sudden deceleration of fast moving electrons when they collide and interact with the target anode. In this process of deceleration, more than 99% of the electron energy is converted into heat and less than 1% of energy is converted into X-rays.
