Changes in the transparency of lead tungstate crystals under continuous ∼1200-h irradiation with γ rays of a radionuclide Co source were investigated. The crystal temperature was maintained at a level of −15°C at a dose rate of 0.1 Gy/h. The crystal transparency recovery process was investigated after the irradiation at temperatures varying from −15 to +38°C. The study was performed while preparing for the PANDA experiment in the FAIR project in Germany.
