An experiment of muon radiography at Mt Etna (Italy) [PDF]

Geophysical Journal International, 2013
Interactions of conduit geometry with gas–liquid flows control volcanic activity, implying that the evaluation of volcanic hazards requires quantitative understanding of the inner structure of the volcano. The more established geophysical imaging techniques suffer from inherent ambiguity, may require spatially dense measurements in active areas and may

Microscale Heterogeneity in Fluid Distribution Patterns During Drainage of a Homogeneous Sand: Neutron Imaging Visualization and Model Limitations

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract We use neutron radiography to provide high‐resolution images of water distribution patterns inside the pore space of a uniformly packed sand in a flow cell, during drainage, induced by a sequence of suction tensions. The experiments reveal the emergence of heterogeneous water distribution patterns within the pore space of the sand, although ...

Analytical Model for Estimating the Zenith Angle Dependence of Terrestrial Cosmic Ray Fluxes. [PDF]

PLoS ONE, 2016
A new model called "PHITS-based Analytical Radiation Model in the Atmosphere (PARMA) version 4.0" was developed to facilitate instantaneous estimation of not only omnidirectional but also angular differential energy spectra of cosmic ray fluxes anywhere ...

Branched Conduit Structure Beneath the Active Craters of Sakurajima Volcano Inferred From Muography

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Observing in‐conduit physical mechanism underlying the switching of eruptive activity between the craters of multi‐vent volcanoes could contribute to hazard assessment at these complex volcanic edifices. We performed monitoring of mass density changes beneath two active craters of Sakurajima volcano in Kyushu, Japan between September 2018 and ...

Nuclear Waste Management: A Mini Review on Waste Package Characterization Approaches

Science and Technology of Nuclear Installations, Volume 2024, Issue 1, 2024.
The characterization of nuclear wastes is the first step toward their efficient management, as the efficient identification of the chemical, physical, biological, mechanical, and/or radiological properties of these materials is crucial to optimize their management scheme. In particular, the radiological characterization of the nuclear waste packages is

The ScIDEP muon radiography project at the Egyptian Pyramid of Khafre

Journal of Applied Physics
The ScIDEP Collaboration is constructing muon telescopes based on scintillator technology to investigate the internal structure of the Egyptian Pyramid of Khafre at Giza near Cairo using cosmic-ray muons. The collaboration aims to scan the pyramid from multiple viewpoints, both inside the king’s burial chamber that is located centrally at the base of ...

Imaging the inner structure of a nuclear reactor by cosmic muon radiography [PDF]

Progress of Theoretical and Experimental Physics, 2019
We studied the inner structure of the nuclear reactor of the Japan Atomic Power Company (JAPC) at Tokai, Japan, by the muon radiography. In this study, muon detectors were placed outside of the reactor building. By detecting cosmic muons penetrating through the wall of the reactor building, we could successfully identify the objects such as the ...

Imaging of underground cavities with cosmic-ray muons from observations at Mt. Echia (Naples)

Scientific Reports, 2017
Muography is an imaging technique based on the measurement of absorption profiles for muons as they pass through rocks and earth. Muons are produced in the interactions of high-energy cosmic rays in the Earth’s atmosphere.
