Muon Detection
December 23, 2023 Admin

Am I getting correct muon counts with my two muon detectors at LRO in coincidence mode? Do other sources of muons affect the detectors from the ground and do we need to take account of these?

Dr Jonathan Lister: We do get upward directed muons their source being radioactivity from soil, rocks and building materials and
