Algorithm for Computational Age Dating of Nuclear Material for Nuclear Forensic Purposes

The parent and daughter nuclides in a radioactive decay chain arrive at secular equilibrium once they have a large half-life difference. The characteristics of this equilibrium state can be used to estimate the production time of nuclear materials. In this study, a mathematical model and algorithm t...
