Nuclear accounting needs a clearer spectrum
Quantum sensors distinguish overlapping radiation signals.

NIST’s September 10 report detailed measurements of uranium, neptunium and plutonium X-ray energies to clarify gamma-ray overlap. [1]
NIST’s separate spectroscopy project describes sensors that measure the energy of individual photons. A superconductor near its transition acts as an unusually sensitive thermometer: deposited energy changes the electrical response, allowing fine spectral distinctions. [2]
The project’s history records deployment of a NIST spectrometer at Brookhaven in 2010. The September result applies that measurement approach to a specific accounting problem, rather than demonstrating that the entire sensing technology appeared overnight. [2]
Bulky refrigeration prevents handheld use; faster accounting and lower costs remain potential benefits, not demonstrated facility savings. [1]
