Experiments are described that show that some of the coincidences between three Geiger counters in a vertical line separated by a considerable thickness of lead are not due to the passage of a single ionizing particle through the three counters but rather to secondary particles released in the lead near the counters. The experiments enable an estimate of the magnitude of this effect to be made.
