Critical infrastructure is aging and deteriorating. To protect initial investments, keep the benefits of structures and minimize the environmental impact, the owners need to make sustainable decisions. To do so, owners need accurate and reliable information on the internal integrity of their buildings, bridges and tunnels. There are several technical solutions available in the market, but unfortunately, there is still a gap in even obtaining accurate geometrical data without destruction. Current technologies face difficulties measuring structures with large cross-section.


Using novel Atmospheric Ray Technology (ART), GScan is able to detect material density and atomic data. For the detection, ART scanners use only highly penetrating natural particle flux (Atmospheric-ray muons). Combined with the patented material detection algorithm, GScan can construct an accurate 3D model of the inner geometry of any critical structure, from bridges to nuclear reactors. With more accurate geometrical information, the asset owners can determine how to make the most out of existing structures.

Contrary to conventional X-ray imaging techniques, GScan’s solution is passive, highly penetrative, and enables automatic material detection by using only naturally-occurring Atmospheric Rays. These are harmless to humans and in addition to non-destructive testing, ART is considered beyond the state-of-the-art technology in security, medical and industrial scanning.


GScan's service is designed to be delivered through local resellers, typically infrastructure inspection and structural assessment companies. Their Key Customers are critical infrastructure asset owners or operators. Their first project is a measurement of an abandoned Soviet nuclear reactor compartment in Estonia, with the objective to prepare the decommissioning procedure to minimize potential hazards and risks associated with safe disposal of the reactor. Furthermore, an agreement has been signed with Estonian green energy company Enefit Green to develop non-destructive testing methods for wind turbines.


Gscan has a total of 35 employees (six with PhD) including founders. The team is a combination of scientists, engineers and experts from physics, civil engineering, IT and security.

Unique selling point

Gscan is building one of the first muon tomography 3D scanners in the world with a patent for their detection algorithm. They are far ahead of their competitors by having their precise detector-building robotic line ready and in production. The laboratory prototype was built and successfully tested in 2020 to prove their technology and they are releasing their industrial prototype in Q1 2023.

Asia Connection

GScan has strong business relations with Japanese companies Kuraray and Hamamatsu. These companies produce key components for GScan’s detectors. Gscan is looking for funding, acquisition opportunities, and talent from across the East Asian region.
