摘要：

This paper describes the development of a portable neutron-gamma detector for environmental radiation monitoring based on the CLYC crystal. It can function as a gamma spectrometer, gamma dosimeter, and thermal neutron counter. The upper measurement limit of gamma dose rate is approximately 6 mSv/h by using the proposed current mode in CLYC crystal and PMT. Meanwhile, the detector has a gamma energy resolution of 4.86% at 662 keV, and a figure of merit (FOM) of 3.32 +/- 0.04 for gamma and neutron pulse shape discrimination. In the initial phase of applications, the detector was used to measure the gamma and neutron radiation levels around the beamline of the associated Proton beam Experiment Platform (APEP) and R-dump room at the China Spallation Neutron Source (CSNS).
