Overview
Gamma Reality Inc. (GRI) is an American advanced-sensing technology company headquartered in Richmond, California. It develops and sells real-time 3D radiation mapping, multi-sensor data fusion, and mixed-reality visualization systems designed to protect people from radiological and nuclear hazards. The company's flagship product is LAMP, a commercially available 3D radiation mapping system that detects, localizes, identifies, maps, and images gamma-rays and neutrons. GRI's technologies can be deployed on manned vehicles, robots, or drones for fully mobile situational awareness, and they automatically fuse data streams from multiple sensors into a single intuitive map that can be viewed in 3D, in real time, and in mixed reality. The founding team developed GRI's core 3D radiation mapping, scene data fusion, and visualization technologies, including the LAMP system, as researchers at a U.S. Department of Energy national laboratory. Over the years they conducted dozens of research measurement campaigns and demonstrated the technologies around the world, including in Fukushima Prefecture, Japan, and in the Chernobyl Exclusion Zone. Feedback from radiation detector operators, first responders, and CBRNE specialists convinced the team that these 3D radiation mapping technologies were a game changer for radiation detection, assessment, and response. Inspired by these experiences, they launched Gamma Reality Inc. to make the technologies commercially available, successfully commercializing them in 2020. GRI's products are now deployed around the world, including in nuclear facilities. The company serves applications such as nuclear power, decommissioning, environmental monitoring, CBRN response, public safety, and safeguards. Its team of scientist-entrepreneurs has extensive experience in radiation detection, computer vision and software development, and multi-sensor system and custom electronics development. GRI describes itself as mission-driven, aiming to harness the power of multi-sensor data fusion and nuclear technologies to make meaningful impacts in the world through continuous technological innovation and deployment, putting cutting-edge technologies in the hands of people who will use them for impactful missions.
History
Gamma Reality Inc. (GRI) was founded by a team of scientist-entrepreneurs who originally developed the company's core 3D radiation mapping, scene data fusion, and visualization technologies, including the LAMP system, while working as researchers at a U.S. Department of Energy national laboratory. During their research careers, the founders conducted dozens of measurement campaigns and demonstrated the technologies around the world, including in Fukushima Prefecture, Japan, and in the Chernobyl Exclusion Zone. In the field, they repeatedly heard from radiation detector operators, first responders, CBRNE specialists, and others that LAMP would make their jobs easier, safer, and more efficient, and that 3D radiation mapping was a game changer for radiation detection, assessment, and response. Inspired by this feedback, the team launched Gamma Reality Inc. to commercialize these powerful real-time 3D radiation mapping, data fusion, and visualization technologies. The company successfully commercialized the technologies in 2020, and they are now deployed around the world, including in nuclear facilities. GRI is headquartered in Richmond, California, and its team has extensive experience in radiation detection, computer vision and software development, and multi-sensor system and custom electronics development. The company markets innovative, award-winning multi-sensor, robotically-deployed hazard mapping, visualization, and data fusion technologies, and continues to grow its team of engineers and scientists.
