摘要：
In this study, a neutron monitoring system based on a cylindrical He-3 detector was designed and simulated using MCNPX code for the nuclear laboratories that use neutron sources for educational and research purposes. Ac-cording to the simulation results, the monitoring system was experimentally tested with different moderators. Finally, using experimental and simulation results, a monitoring system with appropriate efficiency was built based on the considered detector and, its efficiency was measured in different conditions. The test results show that this system can measure the background radiation of the laboratory environment efficiently.
