Chapter 2 discusses radiation safety and risks. For anyone involved with medical imaging, it is essential to be on familiar terms with radiation terminology.Those who are not will find themselves on unsteady ground either when reading the literature or discussing the particulars of a computed tomography (CT) scan with patients. The numerous terms used to describe radiation dose contribute substantially to the confusion, and the first step to a solid understanding is to use only two or three terms for dose measurement. Otherwise, using the full range of units e.g. Roentgen, rad, rem, Gray, Sievert, and their respective conversion factors will cause confusion. In this book, the terminology of radiation dose will be limited to the most commonly used measurements.
