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 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
- Imaging up to 10x faster than traditional methods
- 360° × 90° gamma/neutron and optical field of view
- Uniform detection sensitivity across full 360°
- Image multiple gamma and neutron sources in single data acquisition
- Remote, rapid and accurate imaging
- Portable, IP54 rated hardware
- 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 security and border protection
- Safeguards and defence
- Nuclear facility operations
- Decommissioning and remediation projects
- Nuclear medicine and radiation protection scenarios
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.
