Neutron Waste Assay

Neutron waste assay systems measure the uranium or plutonium content of waste containers or objects. They can be either PASSIVE (measuring spontaneous fission neutrons) or ACTIVE (measuring induced fission neutrons).

Neutron counting technologies include: Total neutron counting (the total neutron count rate arising from a sample), Coincidence neutron counting (the rate of emission of two neutrons in coincidence) and Neutron multiplicity counting (the rate of emission of three neutrons in coincidence).
