Affordable and search from millions of royalty free images, photos and vectors. But not all radiation that is around is dangerous. By adding detailed images, IGRT ensures the powerful radiation is narrowly focused at the treatment area. By bringing a source of gamma radiation close to the glass of a cloud chamber, electrons are ripped from glass molecules and shot inside the chamber. The right image is the ultraviolet emission of the sun. Radiation therapy uses high-energy beams of radiation to control cancer and noncancerous tumors. This article discusses CT radiation dose, the measurement of CT dose, and CT image quality. Gamma radiation is not directly visible in a cloud chamber because it is an electromagnetic wave radiation and not a ray of charged particles. A radiation burn, also called a cutaneous radiation injury (CRI), is a serious medical condition, but thankfully also a rare one. Image-guided radiation therapy (IGRT) is a method of radiation therapy that incorporates imaging techniques during each treatment session. The use of color in these "false-color" images is only used as an aid to show radiation intensity at one particular wavelength.
