Ionic Ce-doped xerogel of silica is synthesized for gamma ray detecting by the sol–gel method and subsequent densification in an inert gas (argon) atmosphere. The optical characteristics may be enhanced by sintering the xerogel in an argon gas, i.e., with a procedure that increases the photoluminescence quantum yield due to a greater concentration of Ce+3 ions. A glassy rod is fabricated at elevated temperatures for the specimen, which is later utilized for gamma ray radiation monitoring. The strength of the radioluminescent signal in the Ce-doped rod increases significantly with escalating dosages of gamma rays till it approaches 500 rad, making this material a viable choice for radiation detection utilization in hostile environments.

KEY WORDS: xerogel of silica, gamma ray detection by radioluminescent signal
