Portable HPGe Gamma- & X-ray Spectrometer

  • Портативный спектрометр гамма-излучения на основе детектора из ОЧГ


Spectrometers based on HPGe (high purity germanium) detectors are designed to detect gamma radiation in the energy range from 40 keV to 3 MeV for GCD models and from 3 keV to 3 MeV for GCDX models.
