High temperature type NaI(Tl) scintillators is a kind of high demanding scintillators with high temperature resistance, vibration resistance and shock resistance design, and the most high quality NaI(Tl) crystals are selected to be used in this type of the scintillators, it is widely used in the well-logging applications, under the harsh environment of high-temperature, high pressure and high humidity, to measure the energy spectrum of Gamma ray. They are suitable for Measurement While Drilling(MWD), the operating temperature range is optional at: 20℃~100℃, -20℃~150℃ and -20℃~175℃.
