Pug-7N Fast and Slow Neutron Detector

Pug-7N fast slow neutron detector by TAPortable Survey Meter

The PUG-7N is a complete fast-slow neutron monitor. The Neutron PUG' detects fast or slow neutrons by means of a thermal neutron scintillation detector and a moderator. When the detector (Model # PNS-20) is external to the moderator, thermal neutrons are detected and measured by means of counts produced in the scintillation detector as read on the meter of the  instrument. The polyethylene moderator is surrounded by a cadmium shield. The cadmium shield absorbs thermal neutrons and allows other neutrons to enter the moderator. The moderator thermalizes the entering neutrons thus allowing them to affect the scintillation detector. 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.


The system includes the PUG-7, four-range survey meter with attached detection system. Ranges are 0-500; 5,000; 50,000; and 500,000 cpm. Detection system includes PNS-20 plus moderator with polyethylene inner sleeve and cadmium outer shield.
