Gamma-ray Spectrometer
 

 

 

- Number of equipments : 5 sets
- Use : measurement and analysis of gamma-ray emitting nuclides and of element
- Equipment : HPGe detector(20 ¡­ 35% efficiency) and Multichannel Analyser
- Two sets of spectrometer with automatic sample changer are used for measuring
   long-lived nuclides up to 40 samples and the rest three sets are operated for
   measuring medium and short-lived nuclides.
- Measurement range of gamma-ray energy : 50 ¡­ 3500 keV
