Abstract
The agents responsible for the production of bursts of ionization in small chambers have been analyzed on the basis of observations taken at 3510-meters elevation. Three methods of separation were employed: (1) the coincidences between ion chambers and between chambers and counters, (2) the variation of burst rate with a small thickness of lead placed over the chamber, and (3) the variation of burst rate with the size of the ionization chamber. Three components of the burst distribution curve are identified with (1) small locally produced electron showers, (2) nuclear disintegrations, and (3) extensive air showers of high density. Each component predominates at a certain range of burst sizes.Keywords
