MAUD Project - development of a new portable detector for alpha and beta surface contamination imaging

Résumé

The characterization and the localization of the radiological contamination on surfaces is of first importance for the decommissioning process of a nuclear facility. Yet, there is cur-rently no device capable of giving a real-time image of the surface contamination by et945; or et946; emitters. The MAUD project (supported by the French agency ANDRA) is aiming at develop-ing a new type of portable detector capable of reconstructing the image of the radioactivity, in real-time, on a solid surface.In this paper, we present the technological developments we performed in order to real-ize the prototype of the MAUD project. We discuss the optimization of the detector type, size and thickness as well as the choice of the read-out electronic. The characterization of the detector response to ionizing radiations will be shown and compared to the numerical simulation used during the development.
