DSH Gamma Radioactive Detector

Specifications

 DSHD-71A Flickering Gamma Radioactive Detector

Main Functions 

  DSHD-71, the predecessor of DSHD-71A flickering gamma radioactive detector, is widely used in doing geological census on radioactive minerals for nuke industry as military products in last century. After its turning to civilian product,The instrument is widely applied to gamma ray detection for units in relative line like environment, building materials, radioactive sanitation, commodity inspection, irradiation etc.
