Solarization refers to a phenomenon in physics where a material undergoes a temporary change in color after being subjected to high-energy electromagnetic radiation, such as ultraviolet light or X-rays.
Clear glass and many plastics will turn amber, green or other colors when subjected to X-radiation, and glass may turn blue after long-term solar exposure in the desert.
It is believed that solarization is caused by the formation of internal defects, called color centers, which selectively absorb portions of the visible light spectrum.
In the field of clinical imaging, with sufficient exposure, solarization of certain screen-film systems can occur which obscures details within the X-ray image and degrades the accuracy of the diagnosis.
