Detection of Bulk Explosives: Advanced Techniques against Terrorism contains reviews of: existing and emerging bulk explosives detection techniques; scientific and technical policy of the Federal Border Service of the Russian Federation; challenges in application and evaluation of EDS systems for aviation security; multi-sensor approach to explosives detection. There are also reports devoted to the following individual explosive detection techniques: X-ray systems in airports; neutron in, gamma out techniques; neutron and gamma backscattering; nuclear quadruple resonance, including remote NQR; sub-surface radars; microwave scanners; laser-induced burst spectroscopy (LIBS); acoustic sensors; nonlinear location (NUD); systems for localization and destruction of explosive objects. While the long term goal - 100 per cent detection, 0 per cent false alarms - is an "impossible" dream, the short term goal - improvement of current detection systems - is achievable in a timely and cost-effective manner. While in some scenarios the general direction of work is to reduce the inspection time, in other scenarios time will be sacrificed in favor of 100 per cent detection probability. Strengtheni
