Real time separate gamma and neutron dose, dose rate and alarms.

• Full neutron energy range coverage
• Very good gamma rejection in neutron channel
• Audible and visual alarms
• Very large autonomy
• Hand free, pass-by exchange
• Fully compatible with DMC 2000 hand free readers and dosimetry software

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 50 keV to over 6 MeV gamma range with an unique linearity to over 10 Sv/h.
