Inverse Modelling of Point Sources
Abstract
Content of the work is the development and testing of an inverse modelling scheme for point sources. The scheme uses measured concentrations (e.g., of radionuclides) from a sampling network to infer the location and strength of a point source of these substances. The application which is aimed at is primarily the localisation of nuclear tests in the context of the Comprehensive Test Ban Treaty (CTBT; http://www.ctbto.org). It could also be used in the case of other (nuclear) emergencies, such as reactor accidents or other accidental releases. A Lagrangian particle dispersion model will be used to infer source-receptor relationships. Based on these, the source fitting the observations best using these source-receptor relationships will be sought by suitable algorithms. The method will be tested on the ETEX and Algeciras releases, and in a hypothetical setting with the CTBT radionuclide monitoring network. The latter application will be a joint exercise with the Atmospheric Environment Service of Canada, the Provisional Technical Secretariat der CTBTO in Vienna, and various meteorological services around the world who co-operate with CTBTO.
