Coloring Characteristic of Lead Glass for X-Ray Irradiation
2015
The lead glass used in an X-ray examination room is indispensable for watching a subject being tested or a situation of operation of an X-ray generator, but because it is some structure equipment of an X-ray examination room, it must obey legal restrictions. Although the standard for lead glass is determined by the International Electrotechnical Commission (IEC), there are few reports about the characteristics related to interaction with radiation. We performed a comparison of three lead glass products, which are principally used in world. As for three products, differences are not looked by physics and chemical characteristics features. Simply the difference was looked by the coloring characteristic for an interaction with radiation. Furthermore, we checked that temporal decolorization of coloring had two half-lives. The short half-life is about 28 hours and the long half-life is about 107 days.
