Sodium Iodide crystals doped with Thallium (or NaI(Tl) crystals) have a very high scintillation or luminescence efficiency and a good energy resolution, NaI(Tl) scintillators has the largest light-out and an emission range well matched to photomultipliers with bialkali photocathodes at a high efficiency, and combination with its easy availability of variety size and geometries and low cost, NaI(Tl) scintillators has become most widely used scintillators. NaI(Tl) crystals is a kind of highly hygroscopic materials, it must be put in a hermetical sealing housing in using.
Well-logging is done in harsh environment of high temperature, high pressure and high humidity, the energy spectrum of Gamma ray needed to be measured in well-logging. Hangzhou shalom EO select the high quality temperature resist NaI(Tl) crystals as the scintillators, use Titanium alloy as housing and Sapphire as optical windows to make the rugged well-logging NaI(Tl) scintillators, and combined with anti shock and vibration design, our encapsulated well-logging NaI(Tl) crystals has a good reflects from well-logging equipment customers.
