Main applications

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