Source-Term Determination of Radionuclide Releases by Inverse Atmospheric Dispersion Modelling (STRADI)
Annotation in Czech
The overall goal of this project is to develop inverse methods for determining the source term of a nuclear accident, which are suitable for both real-time application and assessment of environmental damages. Specific objectives are to (1) develop a method of source term determination that is capable of using all available information, including: i) activity concentration measurements, ii) deposited activity observations, and iii) gamma dose rate observations, as well as a priori source term information. (2) improve the mathematical-statistical inverse modelling methods to allow accurate evaluation of the posterior uncertainty of the results and joint estimation of as many tuning parameters as possible. These could include highly uncertain dispersion model parameters such as wet scavenging coefficients. (3) test the developed algorithms and methods at the example of the Chernobyl and Fukushima disasters, with the ambition of providing source terms of improved accuracy compared to existing estimates. (4) test the developed mathematical-statistical methods for the source term determination of another hazardous substance, e.g., volcanic ash.

Project results evaluation
The success of the STRADI project was based on the combination of expertise on inverse modelling (at UTIA) and atmospheric dispersion modelling (at NILU). This combination produced novel methods and improved tools and data of great use for science as well as regulatory bodies. In addition, the project has published extensively in very well considered top journals, allowed young and female researchers to participate in a good manner and established solid cooperation between the international research teams involved. The overall project rating is outstanding.
