NaI(T1) Scintillation Detector

Of all the scintillators existing in the market, the NaI crystal activated with thallium, NaI(Tl), is the most widely used for the detection of gamma and X rays. NaI(T1) scintillation detector is used when the energy resolution is not the most important factor of the measurement. It can be obtained in almost any shape and size.  NaI(T1) detectors are offered in the market today either as crystals that may be ordered to size or as integral assemblies mounted to an appropriate photo- multiplier tube. The integral assemblies are hermetically sealed by an alu- minum housing.



  • NaI Crystal on the different sizes
  • Photomultiplier tube
  • Preamplifier base
  • Preamplifier
  • Aluminum body and thin aluminum window
  • High efficiency
  • Cheaper than semiconductor detectors
  • SHV connectors
  • BNC connector for output signal



This detector, along with a MCA, H.V. power supply and software and amplifier have various applications such as:

Spectroscopy of gamma and X rays

Educational and research applications

Radiation protection & environmental monitoring

Inspection of cargo

Industrial applications

Nuclear medicine and security controls

Gamma radiation count
