A CO-60 source was placed 2" from the center of a detector, which was shielded from cosmics by 4" of lead, except for right below the source, where there was small pin hole through the lead. Directly above the source lied a finger detector that was placed in coincidence with either PMT.
PMT threshold: 40 mV
Finger Threshold: 30 mV
