He-3的主要用途之一是用于中子探测的气体比例计数器。为国土安全和核扩散检测应用部署的大型辐射探测系统使用这种系统。由于3He用于国土安全和基础研究的大幅增加，供应已经减少，不再能满足需求。这导致了寻找替代技术来取代基于He-3的中子探测器的使用。在这篇文章中，我们回顾了目前在各种国家安全应用中使用的大系统中可商业使用的中子探测替代技术的测试。(C)2010爱思唯尔B.V.保留所有权利。
One of the main uses for He-3 is in gas proportional counters for neutron detection. Large radiation detection systems deployed for homeland security and proliferation detection applications use such systems. Due to the large increase in use of 3He for homeland security and basic research, the supply has dwindled, and can no longer meet the demand. This has led to the search for an alternative technology to replace the use of He-3-based neutron detectors. In this paper, we review the testing of currently commercially available alternative technologies for neutron detection in large systems used in various national security applications.
