In this investigation, some of the properties of the radiation which produces penetrating showers in its passage through matter are studied. Geiger techniques are used to measure the average distance over which the neutral radiation produces one penetrating shower. This distance, called collision length, is measured in water...

The collision length, on the other hand, is measured by placing the material near the apparatus and measuring the mean distance in which one shower is produced and eliminating from the observation any penetrating showers which may be produced subsequently either (a) by the original particle or (b) by the secondaries from the first shower (cascade). This method, as applied to the collision length in water of the neutral penetrating shower producing radiation (NPSPR) forms the main part of this dissertation and is discussed in detail in the following chapters.
