NaIL Dual Detection Neutron-Gamma Scintillator

• Up to 57% efficient for thermal neutrons
• Similar gamma-ray performance as standard NaI(Tl)

NaIL is a game-changing scintillation material for gamma-ray and neutron dual detection. ⁶Li (95% enriched) co-doping introduces efficient thermal neutron detection to the most established gamma-ray scintillator while retaining the favorable scintillation properties of standard NaI(Tl).

Sodium Iodide crystal co-doped with Thallium and Lithium [NaI(Tl+Li)] a.k.a. NaIL^TM has the ability to detect Gamma radiation and Thermal Neutrons in a single crystal with exceptional PSD [FoM = 3.0].

An excellent solution for area monitoring or thermal neutron activation security application.

The use of low ⁶Li concentrations in NaIL and large thicknesses can achieve the same neutron detection capabilities as ³He or CLYC or CLLB detectors at a lower cost.

⁶Li (95% enriched) co-doping introduces efficient thermal neutron detection to the most established gamma-ray scintillator while retaining the favorable scintillation properties of standard NaI(Tl).  NaIL can provide large volume, single material detectors for both gammas and neutrons at a low price per volume.

The Neutron Detection efficiency for NaIL crystals is tested with the crystal placed in a High-Density Polyethylene (HDPE) and a Cf-252 source.  Read the details in this whitepaper Neutron Detection Efficiency Testing.
