Abstract :
Muon-tomography (MT) scanners are built and operated to detect the smuggling of contraband in cargo. Simultaneously with cargo scanning, MT systems can be used to measure naturally occurring changes in cosmic radiation. Our commercially-available MT system detected the decrease in muon flux following the 6 March 2012 coronal mass ejection. We discuss the practical implications for cargo scanning posed by variation in background cosmic radiation.
