The DMC 2000 GN 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 a high sensitivity and very good gamma rejection, tested to 6 MeV. In addition, a gamma section identical to the proven solution of the DMC 2000 S, allows to measure the gamma dose from 50keV to over 6 MeV gamma range with an unique linearity to over 10 Sv/h.
