HPGe Spectrometer with Lead Shield
Description
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.

Application
Used to measure the specific gamma radiation of radionuclides from various types of environmental objects such as rocks, minerals, sludge, slag, soil, plant, sediment and particulate matter in air and water.
Features
- High efficiency of radiation detection
- Radionuclide identification and determination of their specific activity
- Separate and simultaneous measurement of activity of 100 radionuclides
Precision
- Adopting precision gamma-spectrometry methods
- Low level of instrumental background
- Low threshold for radionuclide detection
Reliability
- Excellent peak symmetry
- High count rate indicator
- High energy rate up to 200000 MeV/sec
- HV supply protection if detector is warm
