Abstract: A device for signalling into the environment the status of a radio transmission apparatus, and in particular of an apparatus provided with an X-ray tube, such that the signalling device includes:—a first part, capable of being connected at the power cable of the transmission apparatus, and includes means for measuring the current demand of the transmission apparatus, processing means for determining the status,—switched off, on standby, or in use—of the transmission apparatus depending on the current measurement and means for transmitting the detected status to a second part,—a second part including means for signalling the status of the transmission apparatus detected by the first part.

Abstract: A device for measuring a radioelectric dose on a surface, in particular for measuring the radiological dose for a patient during a radiology operation comprising a matrix with sensors equipped with transparent radio antennas, capable of creating an electric signal corresponding to the electromagnetic radiation received, means for measuring the electric flows emitted by each sensor and means for processing the flow measurements for calculating the accumulation of doses received by predetermined zones of the matrix.
