Zinc Sulfide and Lithium based Neutron Detectors

Neutron detection products that are specifically formulated for the efficient detection of neutrons in the presence of gamma radiation. They can be coupled directly to a photomultiplier tube or light guide. A variety of detector materials are offered for Thermal and Fast Neutron detection

These can be grouped into two categories according to their response to neutron and gamma radiation:

Fast Neutron Detection

• BC-720 consists of ZnS(Ag) phosphor embedded in a clear hydrogenous plastic.

Thermal Neutron Detection

• BC-702 is a matrix of a lithium compound enriched to 95% ₆Li dispersed in a fine ZnS(Ag) phosphor powder.
• BC-704 is a phosphor screen based on ZnS(Ag) and ₆Li.
• BC-705 is a phosphor screen based on zinc sulfide activated with copper, i.e., ZnS(Cu)
• NeuPort / NeuTruck is a ₆LiF/ZnS(Ag) based neutron detector to replace He3 tube in Radiation Portal and Mobile Monitors.  Proprietary Pulse Shape Discrimination (PSD) algorithm is employed to count neutrons and reject gamma ray events.
