The DORIAN code for the prediction and analysis of residual dose rates due to accelerator radiation induced activation

The estimation of residual dose rates at accelerator facilities is an important task for operational radiation protection. The DORIAN code, based on the FLUKA Monte Carlo simulation code, computes residual dose rates and allows in-depth analysis of the various contributions. In addition, the geometrical configuration can be changed after the irradiation has finished and the dose rate can be recalculated for any step-wise irradiation profile and any cooling time very quickly. Therefore, the DORIAN code is a powerful tool for the optimization of residual dose rates at accelerator facilities.
