A Software Package for Radionuclide Detection Event Analysis

The United Kingdom National Data Centre, on behalf of the UK government, is responsible for handling the analysis and assessment of radionuclide data from the International Monitoring System-the verification system operated and maintained by the Comprehensive Nuclear-Test-Ban Treaty Organisation. A series of custom-developed software packages have been implemented for the analysis of both Noble Gas and Particulate sampling data and the subsequent source parameter estimation of radionuclide detection events. These include a radionuclide pipeline for the download, analysis, sorting and archiving of radionuclide data, as well as an atmospheric transport modelling pipeline for performing simulations at varying degrees of fidelity. A new software package, CARVE, provides the capability to interrogate radionuclide detection events and assess their relevance in the context of the Treaty using interactive mapping.
