Description
Jana Vasiljević, Vivian Peters, Anders Puranen, and Bo Cederwall report, in a 2024 paper, a sharper way to image hidden actinides inside shielded waste drums. Old waste was often packed away decades ago with thin or clashing paperwork. Sorting it for safe storage and final disposal demands knowing where uranium and plutonium hide, without opening the drum.
Their method, neutron-gamma emission tomography, listens for paired neutrons and gamma rays born in the same fission event. Fast scintillators catch the pairs, and their timing pins each burst in three dimensions. The scan is passive and has no moving parts. Tests on legacy-type waste showed sensitive detection and location of fission material. Better maps mean safer routing of drums and stronger safeguards checks.
