Title
  • Helicopter-borne Radiometrics (HRD)
  • Hubschrauber-Radiometrie (HRD)
Description
  • Der BGR-Messhubschrauber (Sikorsky S-76B) wird zur aerogeophysikalischen Erkundung des Erduntergrundes eingesetzt. Das Standardmesssystem umfasst die Methoden Elektromagnetik, Magnetik und Radiometrie. Das passive Messsystem der Hubschrauber-Radiometrie (HRD) besteht aus einem Gammastrahlenspektrometer, das sich im Hubschraubers befindet. Der Detektor des Spektrometers hat fünf Natriumiodid-Kristalle (Volumen: 4 l pro NaI-Kristall). Gemessen wird das Spektrum der Gammastrahlung im Bereich von 0 bis 3 MeV. Als Ergebnis werden die Totalintensität und die (Äquivalent-) Gehalte von Thorium, Uran, Kalium sowie die Ionendosisleistung am Erdboden dargestellt.
  • The BGR helicopter (Sikorsky S-76B) is used for airborne geophysical surveying of the Earth’s subsurface. The standard equipment comprises the methods electromagnetics, magnetics and radiometrics. The passive helicopter-borne radiometric (HRD) measuring system is a gamma-ray spectrometer, which is installed into the helicopter. The detector of the spectrometer consists of five Sodium-iodide crystals (volume: 4 l per NaI crystal). The spectral range of gamma radiation recorded ranges from 0 to 3 MeV. The results are displayed as total count rate and the (equivalent) concentrations of Thorium, Uranium and Sodium as well as the exposure rate at ground level.
