AN EXPERIMENTAL STUDY OF THE INDUCTION OF GAMMA-EMITTING ACTIVITIES IN SEVERAL AMERICAN SOILS BY NEUTRONS OF VARIOUS ENERGIES

摘要

The purpose of this work was to study the activation induced in several soils by neutrons of various energies.nTwo nuclear reactors were used as sources of neutrons. The gamma rays resulting from the activity induced in the soils were measured with a 20-channel, differential pulse-height analyzer. The resultant spectra were then analyzed to determine the amount of activity produced by a known neutron flux.
