Terrorist attacks have nowadays become a serious threat, and this threat only continues to grow. The objects of transport infrastructure are among the primary targets for such attacks. We review the existing means of detecting the transportation of dangerous materials and illicit objects and show that no systems are available that completely meet the requirements of homeland security and are simultaneously cost-efficient for cargo inspection. The current equipment is either both bulky and very expensive, does not provide completely reliable inspection results, or demands a time-consuming inspection procedure requiring several types of scanner (which is unacceptable given the huge and permanently increasing volume of transported cargo).We compare various techniques of detecting the transportation of dangerous materials and illicit objects, discuss how they correspond to the current needs, and propose a possible solution to the existing serious problems.As the next step towards the reliable detection of dangerous materials in large cargoes we propose development of an integrated system that combines the best features of the most developed technologies; namely, X-ray analysis (providing the high-speed monitoring and identification of suspicious objects and areas) and neutron analysis (providing high selectivity and precise identification). Such a layered approach would allow the avoidance of the unnecessary scanning of all objects in the active interrogation mode, thus reducing the inspection time. Moreover, it makes it possible to clarify all suspicious areas in the container via a single system inspection.RatecLab Ltd develops universal detection system of high resolution gamma spectroscopy for tagged neutron analysis with time-of-light filtering (Skolkovo Grant 2014-2015). Neutron analysis system equipped with our high resolution spectroscopy platform will give most reliable answer on dangerous substance detection in large dimensions cargo. We demonstrate some characteristics of the developed platform.
