A system for determining the U-235 and U-238 content in a box of radioactive waste material. The system utilizes a passive arrangement which detects spontaneous gamma ray emission from the material in combination with an active arrangement including a neutron source for activating the material.

Automated monitoring of fissile and fertile materials in large waste

An apparatus and method for measuring the neutron moderating or absorbing properties of objects or materials in which a fast neutron source cooperates with a neutron absorbing material which reduces the energy of the fast neutrons by inelastic scattering so that they can be readily thermalized by a moderator. A thermal neutron detector is disposed adjacent the material and serves to detect thermal neutrons emitted by a moderator placed to receive and thermalize the reduced energy neutrons. A material whose absorption is to be measured is placed between a moderator and the detector.
