Muon Tomography Applied to a Dense Uranium Deposit at the McArthur River Mine.
Doug Schouten, PhD, CRM GeoTomography Technologies Inc.
Muon radiography is a means of inferring density by measuring the attenuation of muon (a type of elementary particle naturally abundant from cosmic ray radiation) flux through matter. Muon tomography uses tomographic methods to derive 3D density maps from multiple muon flux measurements.
Measurements of the muon flux were first used by E. P. George (1955) to measure the overburden of a railway tunnel, and by Alvarez et al (1970) in searches for hidden chambers within pyramids. More recently, muon radiography has been used in volcanology, and has also been considered for industrial and security applications. CRM Geotomography Technologies, Inc. (CRM), a spin-off from TRIUMF, is bringing muon tomography technology to bear in mineral exploration.
