Radiation bio effects and dose reduction strategies


Journal Article (Chapter)

Radiation is ubiquitous. It comes from many sources, including cosmic radiation as well as radon exposure. This natural or background exposure is the largest single source of radiation to the world's population. Radiation is also a necessary component of diagnostic and therapeutic imaging. Since the discovery of the X-ray in 1895, it has been a dramatic and increasing influence on health-care. Medical radiation is also of central importance for another reason. Because radiation has bio-effects, for example as a known carcinogen (this was recognized as such very early in the 20th century), medical providers must understand the potential risks of radiation in medical imaging. Much of what is done in medicine is a risk-benefit balance. The following material will review the risk side of the radiation equation and include mechanisms of radiation injury to tissues, doses of medical radiation, risks of medical radiation and outline strategies to manage radiation dose. © 2008 Springer Medizin Verlag Heidelberg.
