Summary: This publication describes the work undertaken by the Working Group 3 «Application of mo dels for assessing radiological impacts arising from NORM and radioactively contaminated legacy sites to support the management of remediation» of the IAEA’s MODARIA programme. The ac¬ Екологія tivities of Working Group 3 covered three tasks: Task 1: Methodology for risk and safety assessment in support of remediation; Task 2: Development of the Normalysa modelling platform; Task 3: Model–model and model–data comparison studies. Within Task 2, a software tool, NORMALYSA (NORM And LegacY Site Assessment), was designed to simulate radionuclide transport in the en vironment from the source term (e.g. radioactively contaminated land) to the relevant receptors (e. g. residential areas, agricultural areas, water bodies) and to estimate resulting radiation expo sure and corresponding doses to humans. The NORMALYSA software tool consists of a Simulator program engine, which is integrated with a set of program modules organized into five libraries: Sources, Cover Layers, Transport, Receptors, and Doses. NORMALYSA utilizes a number of mo dels that have been used beforehand in the safety assessment of radioactive waste disposal facili ties; for some of the radionuclide migration and transfer processes, it uses models recommended by the IAEA. The NORMALYSA software was developed by Facilia AB (Bromma, Sweden) with the support of the IAEA. It is based on the Ecolego 6 software package, which has been developed for implementing deterministic and stochastic dynamics models. It was further tested and bench marked with other similar software tools (e.g. RESRAD) between 2013—2016 within the IAEA’s MODARIA programme under the activities within Working Group 3. This publication presents the User Manual for the NORMALYSA v.2.3 software tool.
