Our specialist neutron detectors offer excellent neutron/gamma discrimination for low false detection rates. Manufactured in sheet form, which can be tiled to produce large area detectors, our neutron detectors are primarily used in Radiation Portal Monitors (RPM’s) to detect radiation within a container or vehicle.
The detection of thermal neutrons is based on the nuclear reaction
6Li + n → 3H + α + 4.78 MeV
Neutron screens are available in three formulations:
ND is a blue emitting screen with unique low sensitivity to background gamma.
NDg is green emitting which is ideal for CCD imaging.
NDFast has been specifically designed for high rate applications.

Customised to your requirements
Scintacor neutron scintillator screens couple well to light guides. With emission being efficiently collected from both surfaces, exceeding most customers’ requirements. The screens can be supplied as self-supporting sheets as well as mounted to a variety of substrates. The screens can be supplied to custom sizes or moulded into novel constructs.
Typical applications
Fissile material detection in radiation portal monitors
Thermal neutron detection in high energy physics
Neutron radiography in non-destructive testing
Neutron dosimetry
Crystallography
