How can we ensure that during nuclear disarmament the disarmed objects are actually real warheads and not cleverly manufactured decoys, while the real arsenal remains hidden? Such decoys and the ability of current verification technologies to detect them have been discussed intensively in the past. Christopher Fichtlscherer and Moritz Kütt have published the article “Uniqueness, Reproducibility and Discrimination of Nuclear Warhead Gamma Signatures” in the Journal of Science and Global Security. They present different theoretical warhead emission models and analyze possible decoy objects for different verification technologies. Their results point to weaknesses in existing systems and show ways how they can be improved.
