Neutron Interactions with Matter
Neutron Interactions with Matter . P. Rinard . 12.1. INTRODUCTION . How neutrons interact with matter aflkcts the ways in which assays can be pdormed with neutrqs. Neutron interactions with the assay material affkct the interpretation of neutron measurements and limit the amount of fissile material the assay instrument can contain safely.
