The NMS017NG is a portable battery-powered neutron survey instrument ideally suited for field surveys and is up to 3 x more sensitive than other Leake design neutron monitors in use today.
The NMS017NG can be used for dose rate and dose measurements and for neutron counting in 8 modes of operation. Switching between any mode is as easy as pressing a button. Furthermore standard working levels are clearly marked on the analogue display, making it easier for the user to instantly assess their whereabouts in the local working environment.
The moderator consists of a 208mm diameter polyethylene sphere. Neutrons are thermalised by the moderator and detected by the spherical He-3 SP9 proportional counter.
Data is displayed on a digital LCD with back light and an analogue display. All user operations are carried out with two push button mode switches and a rotary on/off switch.
