Well my understanding would be that a fair proportion of your BG at sea level will be muons, the exact proportion will depend upon the concentration of NORM, including radon and daughters, in your locality. GM tubes are certainly detecting muons as they are both highly penetrating and highly ionising. I would suspect the counting efficiency for muons in a GM set up would be close to 100%.
