The proliferation of nuclear and radiological weapons of mass destruction is a serious threat in the world today. The goal of this proposal is to develop a new, very low cost radiation detection technology that will be useful for detection and for surveillance of individuals who have been near radioactive materials. The technology can also be used for dosimetry, and will provide the technology for ...

At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrom ...

A drop-in 3He-tube replacement technology for thermal neutron detection does not exist today. It is critical for homeland security and nuclear safeguards applications. In this program, Triton Systems proposes to develop a light-weight, large-area, high efficiency portable neutron detector for passive interrogation using an innovative gas detector structure. The resulting 3He-free thermal neutron d ...
