Nuclear resonance fluorescence (NRF) is a gamma-ray detection technology that identifies the presence of specific isotopes, including plutonium and uranium. The technique works by irradiating a material with high-energy photons and then detecting the photons which are subsequently emitted. During the nuclear weapon dismantlement process it can be used on high-density containers with thick layers. This technology collects proliferation sensitive information and requires the use of an information barrier.
