NEUTRON STREAMING THROUGH HYDROGENOUS MEDIA

The study of neutron streaming through paraffin is reported herein. This work is essential to the beginning of experiments in which neutrons streaming through air ducts in concrete will be studied. In the study of neutron streaming through paraffin the energy spectra of the flux was measured by the activation of bare and cadmium covered foils, foil sandwiches, and threshold foils. Normalized foil response as a function of paraffin thickness is reported. Described is a sequence of computer programs for processing the radiometric data associated with foil activation. These programs are also suitable for handling other radiometric analysis problems.
