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.
