A radiometric measuring device comprising: a radioactive radiator which sends radioactive radiation through a container; and a detector serving to receive a radiation intensity penetrating through the container, dependent on the physical, measured variable, and to convert such into an electrical output signal. The detector includes a carrier, on which at least one scintillation fiber is wound, which converts radiometric radiation impinging thereon into light flashes, whose light propagates in the respective scintillation fiber toward its ends. The detector further includes at least one array of avalanche photodiodes operated in a Geiger mode, which convert light impinging thereon into an electrical signal. The detector also has a measuring device electronics connected to the avalanche photodiodes for producing the electrical output signal, based on the electrical signals of the avalanche photodiodes. |
