摘要

Scintillation detectors based on LSO, CeF and PbWO are the main candidates for measuring γ- rays in a mixed γ/n pulsed radiation field with high intensity. An experiment using the Lissajous figure method to study the high fluence rate response behavior of three kinds of commonly used scintillators is introduced in this paper. The result shows that the fluence rate linear response limit of LSO and CeF is 1.9 * 10 19 and 2.1 * 10 18 MeV/(cm 2 · s), respectively, and the PbWO scintillator still maintains linea...
