Uranium glass is yellowish green glass which is produced by adding a small amount of uranium as a coloring agent into ordinary glasses. The glass has a characteristic of emitting strong fluorescent light of around 550nm under ultraviolet light. Most of uranium glass was fabricated before World War 2 but still small amount of uranium glass is being fabricated nowadays. In this study, various kinds of uranium glass were subjected to the measurement of the γ-ray by Ge semiconductor detector. It was found that in older glasses (fabricated from the late 19th century to the early 20th century), γ-ray peaks from 214Pb and 214Bi were clearly identified which are in equilibrium with 226Ra that was apparently not completely separated from uranium due to the level of purification technology at that period. From the comparison of gamma peaks of 235U and 234Pa, it was found that many uranium glass samples fabricated after World War 2 use depleted uranium. The content of 40K in uranium glass was found to vary with where specimens were produced.
