CORIS360® GNI - Gamma Neutron Imager

CORIS360® GNI

The CORIS360® Gamma Neutron Imager (GNI) is the world’s only commercial technology capable of imaging both gamma-ray and thermal neutron sources of radiation. With the addition of thermal neutron imaging, CORIS360® GNI delivers a major step forward in nuclear security and safeguards by enabling the detection, localisation and identification of nuclear materials through both their gamma and neutron signatures. This dual imaging capability offers significant advantages for nuclear facilities, defence operations and national security agencies.

Remote, fast and accurate imaging

Utilising innovations in the mask design and its patented compressed sensing technique, CORIS360® GNI images gamma-rays and thermal neutrons up to ten times faster than traditional methods. While it introduces enhanced capabilities, it maintains the same high performance imaging functionality as the original CORIS360® model.

The CORIS360® GNI system offers:

Simultaneous gamma & thermal neutron imaging
360° × 90° gamma/neutron and panoramic optical field of view
Imaging up to 10x faster than traditional methods
Image multiple sources in a single data acquisition
Uniform detection sensitivity across full 360°
Accurate imaging with optical overlay
Portability and remote operation
Two plug-and-play detector modules for optimised performance across varied radiation environments

Applications across the nuclear landscape

CORIS360® GNI is designed for a wide range of applications, including:

Nuclear facility operations
Radiation protection
Safeguards
Decommissioning and remediation projects
Nuclear security and border protection
Defence

Reducing risk and improving efficiency

Traditional radiation scanning often requires workers to perform manual surveys with handheld devices—an approach that can be slow, labour intensive and hazardous. These all increase the risk of unnecessary radiation exposure and user error.

CORIS360® GNI transforms this process. It can be remotely operated, and can scan an entire room, container or asset in a single data acquisition. Operators receive fast, visual, and highly accurate information on both the type and location of radiation sources.

A new benchmark in radiation detection

By combining speed, accuracy and dual modality imaging into a single portable system, CORIS360® GNI represents a major advancement in radiation detection technology—setting a new industry standard for safety, performance and efficiency.

CORIS360® - New radiation imaging solution

Features and benefits

Overlaying a 360° x 90° radiation image onto a panoramic optical image of the scene, makes interpretation much easier. The spectroscopic detector at the heart of the imager enables the accurate visualisation and identification of sources across a broad energy range.

Compressed sensing technology

Using the theory of compressed sensing technology, a team of physicists and scientists invented and developed the CORIS360® platform imaging technology. Compressed sensing imaging can generate an image with far fewer samples compared with traditional imaging techniques.
