ABSTRACT THE main part of the non–ionizing component of cosmic radiation near sea–level consists of photons1 and neutrons2. A rough survey carried out by Rossi and his co–workers3 at
sea–level did not give any evidence of penetrating neutral particles. Experiments of the same type by Rossi and Regener4 at 4,300 m. above sea–level, however, show the existence of a small
number of penetrating neutral particles. We have carried out similar experiments at sea–level with positive results. Access through your institution Buy or subscribe This is a preview of
