The tomography was done at a synchrotron (ESRF), and with beamtime being very expensive it would be a net-negative to scan lottery tickets, unfortunately...
Fortunately for anyone wanting to xray lottery tickets, you don't need the IIRC most powerful beamline in the world. A few years ago a Vesuvius Challenge Community member bought a benchtop xray machine for a few grand and scanned pokemon cards and was able to identify them that way.
