ETCC Complete visualization of Gamma Rays
—Expanding the World of Applications

ERRAI Corporation develops and provides ETCC,
the world's first camera capable of capturing gamma rays just like an optical camera.

Applications

  • Radiation Measurement Decommissioning, Clearance, Environmental Monitoring

    By remotely measuring radiation conditions at nuclear power plants via imaging, we create 3D visualizations of wide-area radiation distribution, including airborne radiation. Data provided by ETCC improves the accuracy of radiation dispersion predictions.

  • Space and Lunar Resource Development Space and Lunar Resource Development

    Our world-first gamma-ray imaging capability was demonstrated in space during a 2018 joint experiment between JAXA and Kyoto University that observed the Milky Way galaxy. By creating lunar resource maps through gamma-ray observation, we contribute to the realization of lunar resource exploration.

MESSAGE

We aim to contribute to the safety
and security of society through
the complete visualization of gamma rays.

We have realized the complete visualization of gamma rays, which have been said to be invisible for 120 years since their discovery.
While various pseudo-gamma-ray imaging methods have been developed since 1980, their use remained very limited as they did not satisfy the basic principles of geometric optics.
Our technology, named ETCC (Electron-Tracking Compton Camera), enables the imaging and visualization of gamma-rays based on the same geometric optics as an optical camera.
This is an innovative technology expected to lead the 21st century, with applications ranging from reactor abnormality detection and medical imaging to planetary resource exploration.
ERRAI Corporation is dedicated to contributing to society by advancing safety and security through ETCC technology within the field of radiation science.
