Understanding the nuclear explosion source

Understanding the nuclear
explosion source

Underlying the design of the Treaty’s verification networks and the entire data processing and event interpretation formalism is an understanding of the nuclear explosion source.  The Treaty’s important provision for on-site inspections requires a priori knowledge of the observables that can be expected after a nuclear test. Contributions are sought in discrimination methods between natural events and anthropogenic explosions across the technologies used in the Treaty’s verification system (seismic, infrasound, hydroacoustic, and global radionuclide detection),  as well as topics germane to enhancing on-site inspection methodology, such as microseismicity at local scales, mechanisms of release and transport of particulates and gases from underground test environments, strategies for noble gas sampling, the temporal evolution of nuclear test signatures, and geophysical and radionuclide characterization of nuclear test sites from measurements and from modelling. Contributions on observational techniques and source characterizations not now in the Treaty’s technical portfolio are welcome.
