From invisible radiation, to social safety and future technology.
ERRAI Corporation is an advanced technology company that brings new possibilities in measurement and visualization to medicine, nuclear safety, security, space and fusion, through the social implementation of ETCC — the world's first fully visualizing gamma-ray camera.
As an advanced technology startup founded out of Kyoto University, we develop and pursue the social implementation of ETCC — the world's first fully visualizing gamma-ray camera.
Through the social implementation of ETCC, we expand the visibility of gamma radiation and contribute to building a safer and more enriched society.
For decades, gamma rays were considered “invisible.” Throughout the 1970s and 80s, multiple pseudo gamma-ray imaging methods were developed around the world. However, these approaches did not satisfy the fundamental principles of optics, and practical applications remained limited.
Beginning in the 2000s, we faced this fundamental challenge head-on and advanced research and development in earnest. The new measurement method we developed — the Electron Tracking Compton Camera (ETCC) — three-dimensionally tracks the trajectory of a scattered electron from a single gamma ray, uniquely determining its incoming direction.
Then, in 2017, we achieved the world's first complete visualization of gamma rays. The following year, we succeeded in directly imaging diffuse gamma rays arriving from the center of our Galaxy. We named this new way of seeing — capable of photographing gamma rays and quantitatively measuring radiation from the resulting image data — ETCC.
Bringing the “safety and certainty” that were once out of reach to medicine, nuclear safety, security, space development, and nuclear fusion — through the social implementation of ETCC — is the mission of ERRAI Corporation.
ETCC's visualization capability has been applied across many domains — from industrial sites on the ground to outer space.
Precise measurement of radioactive waste from nuclear plant decommissioning.
Monitoring nuclear reactor operation and detecting anomalies.
Pharmacokinetic monitoring with radioisotopes and diagnostic imaging.
Detection of nuclear materials in homeland security contexts.
Resource exploration and elemental distribution measurement on the Moon and asteroids.
Plasma measurement and control in nuclear fusion reactors.
ETCC was born on top of a half-century of research into gamma-ray imaging.
Multiple pseudo gamma-ray imaging methods are developed.
Foundational research on the Electron Tracking Compton Camera begins in earnest.
World's first complete visualization of gamma rays is achieved.
Diffuse gamma rays from the Galactic Center are directly imaged.
Application of ETCC continues to expand across medical, nuclear and space domains.
Financial and business development expertise. Decades of fundamental research. Cutting-edge cosmic-ray and gamma-ray observation technology. Three perspectives that together sustain the social implementation of ETCC.
The social implementation of ETCC is supported by financial and business development expertise, decades of fundamental research, and the most advanced cosmic-ray and gamma-ray observation technology.
Our headquarters is located on the Kyoto University campus, inside the International Science Innovation Building.
