The lead glass used in an X-ray examination room is indispensable for watching a subject beingtested or a situation of operation of an X-ray generator, but because it is some structure equipmentof an X-ray examination room, it must obey legal restrictions. Although the standard for leadglass is determined by the International Electrotechnical Commission IEC, there are few reportsabout the characteristics related to interaction with radiation. We performed a comparison ofthree lead glass products, which are principally used in world. As for three products, differencesare not looked by physics and chemical characteristics features. Simply the difference was lookedby the coloring characteristic for an interaction with radiation. Furthermore, we checked thattemporal decolorization of coloring had two half-lives. The short half-life is about 28 hours andthe long half-life is about 107 days.
