Helium-3 (3He) is a necessary component of many nuclear
detection devices; however our country is facing a Helium-3
shortage. To address this shortage, DHS’ Domestic Nuclear
Detection Office (DNDO) is advancing the search for efficient,
cost-effective alternative technologies. After weeks of rigorous
testing, DNDO completed a test campaign for alternative
technologies to smaller Helium-3 dependant radiation detection
systems. During the test campaign, conducted at the Radiological
and Nuclear Countermeasures Test and Evaluation Complex at the
Nevada National Security Site, DNDO evaluated 39 different
neutron detection technologies, such as handhelds, backpacks and
vehicle-mounted equipment. DNDO provided post-test information
to participating vendors to help accelerate device development.
These technologies are being developed through government-
sponsored research or by commercial manufacturers, expediting
product development while reducing government cost. In August
2011, DNDO successfully completed a two-ye
