RADIOMETRIC MEASURING DEVICE FOR CARRYING OUT MEASUREMENTS IN EXPLOSION-PRONE AREAS

The invention relates to a radiometric measuring device for carrying out measurements in an explosion-prone area, which radiometric measuring device requires only little space at the measurement location and can be economically produced. The radiometric measuring device comprises a measuring unit (7) that can be used in the explosion-prone area. Said measuring unit comprises a scintillator (13), which converts radioactive radiation incident on the scintillator into photons, and a semiconductor detector (15), which is connected to the scintillator (13) and can be operated by means of an inherently safe energy supply and metrologically captures photons arising in the scintillator (13) and reaching the semiconductor detector (15), and converts said photons into electrical measurement signals. Explosion protection measures to be associated exclusively with the ignition protection class of the inherent safety are provided in the measuring unit. The radiometric measuring device also comprises a superordinate unit (11) to be arranged outside of the explosion-prone area and to be connected to the measuring unit (7). The superordinate unit effects an inherently safe supply of the measuring unit (7)-in particular, the semiconductor detector (15), during measuring operation.
