Ionising Radiation in Medicine
The benefit to patients from the medical use of radiation has been established beyond doubt.[1,2,3] Modern diagnostic imaging assures faster, more precise diagnosis, enables monitoring of a large proportion of diseases and, in cases of interventional cardiology, also allows therapy. Frequently, radiological procedures have a substantial impact on the speed of diagnosis and are decisive in clinical management.[2,4]
The most common types of ionising radiation used in medicine are X-rays, gamma-rays, beta-rays and electrons.[4,5,6,7,8,9,10,11] Ionising radiation is only one part of the electromagnetic spectrum. There are numerous other types of radiation (e.g. visible light, infrared waves, ultrasound, high frequency and radiofrequency electromagnetic waves) that do not possess the ability to ionise atoms of the absorbing matter.
