产品介绍:NEUTRONDETECTORS中子探测器
Eljen Technology offers three products specifically for neutron detection which possess an intrinsic low sensitivity for gamma radiation. EJ-410 is a detector for fast neutrons, composed of an acrylic disc embedded with concentric rings of ZnS:Ag scintillator. EJ-420 and EJ-426 are detectors for thermal neutrons and both are composed of a matrix of ZnS:Ag and Li6. EJ-420 is offered as a disc, while EJ-426 is offered as either disc or sheet material with a variety of support backing materials.

Eljen Technology offers three different zinc sulfide (ZnS:Ag) coated products for alpha or alpha/beta detection. EJ-440 and EJ-442 are products designed specifically for alpha detection. EJ-440 consists of a polyester sheet coated with ZnS:Ag while EJ-442 consists of a non-flexible support material coated with ZnS:Ag. EJ-444 is designed for alpha/beta detection and discrimination and consists of a thin sheet of EJ-212 plastic scintillator coated with ZnS:Ag.
