WebPhysical and Chemical Analysis and Measurement Slow-neutron detectors. For slow neutrons, the principal conversion methods involve one of the nuclear reactions shown in Table 7.In each case, the reaction is characterized by a positive Q-value, meaning that this amount of energy is released in the reaction.Since the incoming slow neutron has a low … WebThe ANTECH N2223-220 High Efficiency Passive Neutron Drum Monitor a high detection efficiency measurement system for the determination of plutonium mass in intermediate, transuranic or low level waste using passive neutron total coincidence or multiplicity counting, with a high detection efficiency.
