Abstract

This work presents a study on technological advances in nuclear instrumentation, specifically neutron detection and counting, for applications in radiation protection and nuclear security risk prevention. Currently the majority of security monitoring systems use proportional counters filled with 3He helium gas to detect neutron sources. Due to the severe global shortage of 3He, a replacement technology for neutron detection is needed in the near future. Several alternative replacement detectors are available now, among these detectors is the 6LiF+ZnS (Ag) scintillation neutron detector having a large cross section of neutron interaction. In this work we have shown that the 6LiF+ZnS(Ag) scintillator meet the following requirements: a very good sensitivity, excellent stability during counting time, and a quick response from the associated electronic module. These features are sufficient for it to be used in the detection of nuclear and radioactive materials nuclear material and radioactive material that may be used in a criminal or unauthorized act, to ensure nuclear security in the national and international territory.
