Probabilistic methods allow a first analysis, which leads to a hierarchy, in terms of orders of magnitude: one risk deserves to be taken into account, whereas some others may be neglected. Then, according to the needs, one can go further, and ask for a better knowledge of those which have been kept. In this respect, we realized in 2005 a risk analysis for the French "Commissariat à l'Energie Atomique", Saclay center. It dealt with a comparison and classification of risks linked with planes which may fly above the zone, and linked with transportation of dangerous materials, by trucks, near the site. The output of our study was a hierarchy of these risks.
