NaI(Ti) Gamma Crystals
Numbers:FR-111
Main Application:
Products main are two types (Temperature)
·Normal temperature type: -30 ℃~100 ℃; Application: Nuclear radiation, Environmental monitoring, High-energy physics, etc.
·High temperature type: -30 ℃~200 ℃; Application: Oil well logging, Geophysical survey, etc.

NaI (TI) is a kind of scintillation crystal with good performance. It is grown by host material sodium iodide doped with appropriate percentage of thallium. The main emission wavelength is 415nm, which well matched with the working wavelength of photomultiplier tubes (PMT). It has very high luminescence efficiency and exhibits no significant self absorption of the scintillation light and has good resolution ability to X-ray and γ-ray. It can be made into monocrystal or polycrystal with various dimensions and shapes.
*Products main are two types (Temperature)

·Normal temperature type: -30 ℃~100 ℃; Application: Nuclear radiation, Environmental monitoring,
   High-energy physics, etc.
·High temperature type: -30 ℃~200 ℃; Application: Oil well logging, Geophysical survey, etc.
This High-temperature type has good output consistency to used for petroleum logging with three kinds heat resistant performance: 150℃.175℃ and 200℃,.The standard scintillation crystal and Ruggedized scintillation crystal are used in oil exploration equipments.
