The DMC 2000GN takes advantage of a unique licensed neutron detection technology based an large single diode. The full energy range of thermal, intermediate and high energy neutrons is covered with high sensitivity and escellent gamma rejection, tested to 6 MeV. In addition, a gamma section identical to the proven solution of the DMC 2000 S, allows measurement of gamma dose from 50 keV to over 6 MeV with unique linearity to over 10 Sv/h.
