ABSTRACT: 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.
