The PUG-7N-D is a neutron monitoring system for fast and slow neutrons. It features the PRS-7, five- decade survey meter with attached detection system: the MO-1 Moderator, and the PNS-20 Neutron Probe. The PUG-7N-D System, or ``Neutron PUG'' detects fast or slow neutrons by means of a thermal neutron scintillation detector and a moderator. When the detector (PNS-20) is external to the moderator, thermal neutrons are detected and measured by means of counts produced in the scintillator as read on the meter of the PRS-7 instrument. The polyethylene moderator is surrounded by a cadmium shield. The cadmium shield absorbs thermal neutrons and allows fast neutrons to enter the moderator. The moderator ``thermalizes'' the entering neutrons thus allowing them to interface with the scintillator. When the thermal neutron detector is within the moderator, thermal neutrons are excluded by the cadmium layers and the detector measures only fast neutrons which have entered the moderator and been ``thermalized''. Direct measurement of thermal neutrons is available due to the removable detector inside the housing.
