title: ALARA pre-job studies using the VISIPLAN 3D ALARA planning tool.
abstract: The optimisation of the radiation protection for the workers in nuclear industry is an important part of the safety culture. The application of the ALARA concept (to keep exposures as low as reasonably achievable) is not always straightforward as it is influenced by the site geometry, source distribution and work organisation. A good ALARA pre-job study must therefore be performed and should contain predicted doses for the different suggested work scenarios and provide a quantitative basis to select between various alternative work scenarios for a specific operation. In order to handle this information, SCK-CEN developed the VISIPLAN 3D ALARA planning tool. The tool makes it possible to evaluate the dose due to external gamma exposure based on the simulation of work scenarios taking into account worker positions and subsequent geometry and source distribution changes in a three-dimensional environment.
