This new detector at SOLEIL will provide a measurement of the dose received by equipment that are damaged by the radiations in the storage ring, and to anticipate their replacement. This monitor should be very compact to be placed in tiny areas, sensitive to all kind of radiation and low cost to install many of them around the ring. A readout electronic module is being developed in-house, and a first prototype has been build and installed on the machine. Description of the system and first results recorded on the machine are presented.
