Slow neutron detector
WebbPhysical and Chemical Analysis and Measurement Slow-neutron detectors. For slow neutrons, the principal conversion methods involve one of the nuclear reactions shown … WebbThe basic physical principles for neutron detection are the neutron’s characteristic properties and several important nuclear reactions and processes. ... Then there are for slow-neutron detection boron-loaded plastic scintillators (BC-454) and gadolinium (BC-521) and natural (BC-454) or enriched boron-loaded liquid scintillators (BC-523A).
