Abstract Isotopic ratios of radioactive xenons sampled in the subsurface and atmosphere can be used to detect underground nuclear explosions (UNEs) civilian reactors. Disparities half-lives decay chains are principally responsible for time-dependent concentrations xenon isotopes. Contrasting timescales, combined with modern detection capabilities, make isotopic family a desirable surrogate UNE ...

By solving the Marchenko equations, the Green’s function can be retrieved between a virtual receiver in the subsurface to points at the surface (no physical receiver is required at the virtual location). We extend the idea of these equations to retrieve the Green’s function between any two points in the subsurface; i.e, between a virtual source and a virtual receiver (no physical source or phys...
