Simulation of ambient dose equivalent from -rays from radioactive decays with FLUKA and DORIAN

During my stay (29. June- 25. September 2015.) as a participant of Summer Student Programme I was working in Radiation Protection group at CERN. The primary task of my project was to extend the functionality of the DORIAN (DOse Rate Inspector and ANalyzer) code that is used for prediction and analysis of residual dose rated due to accelerator radi- ation induced activation. This task consisted of writing and validating a dedicated FLUKA user routine to simulate the radiation coming from radioactive decays. The results of the FLUKA simulations using this user routine then had to be integrated into the DORIAN code
