| Outline of Final Research Achievements |
We developed cosmic-ray muon radiography with nuclear emulsion. Cosmic-ray muon radiography is a non-destructive inspection for large scale structures. We developed basic technologies and conducted the experiment for several targets. As a result, we achieved the following results. 1. Discovery of unknown big void inside the Khufu’s Pyramid at Cairo in Egypt. 2. Demonstration of imaging of lower part of Hamaoka Nuclear Power Plant. 3. Demonstration of imaging of hollow floor plate. These results validated the methodology of application of several targets (archaeology, industrial plant, civil engineering).
