Operations in a D&D environment are in most cases one of a kind meaning that return of experience is only marginally available for some operations. The problem of being confronted with new environments, operations and risks can be partly solved by the use of a 3D simulation tools combining dose assessment and human motion simulation. This presentation will show how a combined use of a 3D dose a...
