Detection and quantification of trace chemicals is a major thrust of analytical chemistry. In recent years much effort has been spent developing detection systems for priority pollutants. Less mature are the detections of substances of interest to law enforcement and security personnel:in particular explosives. This volume will discuss the detection of these, not only setting out the theoretical fundamentals, but also emphasizing the remarkable developments in the last decade. Terrorist events—airplanes blown out of the sky (PanAm 103 over Lockerbie) and attacks on U.S. and European cities (Trade Center in New York and the Murrah Federal Building in Oklahoma City, railways in London and Madrid)--emphasize the danger of concealed explosives. However, since most explosives release little vapor, it was not possible to detect them by technology used on most organic substances. After PanAm 103 was downed over Scotland, the U.S. Congress requested automatic explosive detection equipment be placed in airports. This volume outlines the history of explosive detection research, the developments along the way, present day technologies, and what we think the future holds. - Written by experts in the field who set out both the scientific issues and the practical context with authority - Discusses and describes the threat - Describes the theoretical background and practical applications of both trace and bulk explosives detection

The fast detection of explosives from the vapor phase would be one way to enhance the protection of society against terrorist attacks. Up to now the problem of detection of explosives, especially the location of explosives whether at large areas e. g. station halls, theaters or hidden in cars, aircraft cargo, baggage or explosives hidden in crowds e. g. suicide bombers or bombs in bags has not been solved. Smelling of explosives like dogs do seems to be a valuable tool for a security chain. In general different strategies can be adopt to the basic problem of explosive detection: • bulk detection • vapor detection Normally meetings cover both aspects and applications of the detection. Even though both methods might fulfill special aspects of a general security chain the underlying scientific questions differ strongly. Because of that the discussions of the scientists and practitioners from the different main directions are sometimes only less specific. Therefore the NATO Advisory Panel in Security-Related Civil Science and Technology proposed a small series of NATO ARW's which focuses on the different scientific aspects of explosives detection methods. This book is based on material presented at the first NATO ARW of this series in Moscow which covered the topic: Vapor and trace detection of explosives. The second ARW was held in St. Petersburg and treated the topic Bulk detection methods. The third workshop was held in Warwick and focused on electronic noses which cover a somewhat different aspect of vapor detection.

Up to now so called sniffer dogs are the most successful and widespread systems for the explosives detection at airports and in public areas. Dogs are able to detect explosives under various conditions. On the other hand dogs are living beings and their behavior and skills are influenced by numerous parameters (e.g. age, sex, trainer, daily condition, etc.). To overcome these problems concerning the detection of explosives and illicit substances by dogs chemical sensors seemed to be a valuable alternative for this application and therefore a valuable tool in counter terrorism. The presented papers are an outcome of an NATO ARW which was hold in Moscow and cover different aspects of vapour and trace detection of explosive. Starting from different scenarios (airport security, inspection of large areas, freight screening, boarding passes, etc.) and taking into account the capability of dogs the chances of and demands on chemical sensors are discussed in view of their possible application. Several papers highlight the capability and possibilities of different methods and devices for the vapour detection of explosives (drift MS, high speed gas analyzers, ion mobility increment spectrometer, etc.). Information about the post explosion identification of explosives by LC/MS and the development of explosive standards for dog training and sensor testing are presented also.

This ARW is the third NATO-sponsored workshop on Explosives Detection and Humanitarian Demining. The previous events were • Detection and Destruction of Anti-Personnel Landmines Moscow, 1997 • Explosives Detection and Decontamination of the Environment Prague, 1997. Over the last decade applied research in Humanitarian Demining has made progress to some extend, but according to the tremendous tasks of Demining and the lack of scientific methods for practical detection of explosive devices, research activities are still of the same importance than ever before. Concerning countermeasures against terrorism the detection of explosives is one of the keyfactors, but the practical applications are not sufficient solved. An international exchange of research results are therefore urgent, to find out the most promising measures for application. The coincidence of this ARW and the terrible disaster of New York and Washington may demonstrate the importance of this task. In consequence the explosive device detection technologies can make a major contribution to collective, family and individual security. In developed countries, these technologies provide a strong deterrent and preventative measure against terrorist threats. In less developed regions, they can improve individual, institutional and state security, lessening the insecurity that motivates many terrorists acts. The elimination of landmine threats is just one of many ways of achieving this. However our attempts to meet the extremely difficult technical challenges posed by landmine and UXO contamination are inevitably leading us to new technological approaches.

Nuclear quadrupole resonance (NQR) a highly promising new technique for bulk explosives detection: relatively inexpensive, more compact than NMR, but with considerable selectivity. Since the NQR frequency is insensitive to long-range variations in composition, mixing explosives with other materials, such as the plasticizers in plastic explosives, makes no difference. The NQR signal strength varies linearly with the amount of explosive, and is independent of its distribution within the volume monitored. NQR spots explosive types in configurations missed by the X-ray imaging method. But if NQR is so good, why it is not used everywhere? Its main limitation is the low signal-to-noise ratio, particularly with the radio-frequency interference that exists in a field environment, NQR polarization being much weaker than that from an external magnetic field. The distinctive signatures are there, but are difficult to extract from the noise. In addition, the high selectivity is partly a disadvantage, as it is hard to build a multichannel system necessary to cover a wide range of target substances. Moreover, substances fully screened by metallic enclosures, etc. are difficult to detect. A workshop was held at St Petersburg in July 2008 in an attempt to solve these problems and make NQR the universal technique for the detection of bombs regardless of type. This book presents the essentials of the papers given there.

Features are extractable measurements from a sample image summarizing the information content in an image and in the process providing an essential tool in image understanding. In particular, they are useful for image classification into pre-defined classes or grouping a set of image samples (also called clustering) into clusters with similar within-cluster characteristics as defined by such features. At the lowest level, features may be the intensity levels of a pixel in an image. The intensity levels of the pixels in an image may be derived from a variety of sources. For example, it can be the temperature measurement (using an infra-red camera) of the area representing the pixel or the X-ray attenuation in a given volume element of a 3-d image or it may even represent the dielectric differential in a given volume element obtained from an MIR image. At a higher level, geometric descriptors of objects of interest in a scene may also be considered as features in the image. Examples of such features are: area, perimeter, aspect ratio and other shape features, or topological features like the number of connected components, the Euler number (the number of connected components less the number of 'holes'), etc. Occupying an intermediate level in the feature hierarchy are texture features which are typically derived from a group of pixels often in a suitably defined neighborhood of a pixel. These texture features are useful not only in classification but also in the segmentation of an image into different objects/regions of interest. At the present state of our investigation, we are engaged in the task of finding a set of features associated with an object under inspection (typically a piece of luggage or a brief case) that will enable us to detect and characterize an explosive inside, when present. Our tool of inspection is an X-Ray device with provisions for computed tomography (CT) that generate one or more (depending on the number of energy levels used) digitized 3-dimensional attenuation images with a voxel resolution of the order of one quarter of a milimeter. In the task of feature extraction and subsequent selection of an appropriate subset thereof, several important factors need to be considered. Foremost among them are: (1) Definition of the sampling unit from which the features will be extracted for the purpose of detection/ identification of the explosives. (2) The choice of features (given the sampling unit) to be extracted that can be used to signal the existence / identity of the explosive. (3) Robustness of the computed features under different inspection conditions. To attain robustness, invariance under the transformations of translation, scaling, rotation and change of orientation is highly desirable. (4) The computational costs in the process of feature extraction, selection and their use in explosive detection/ identification In the search for extractable features, we have done a thorough literature survey with the above factors in mind and come out with a list of features that could possibly help us in meeting our objective. We are assuming that features will be based on sampling units that are single CT slices of the target. This may however change when appropriate modifications should be made to the feature extraction process. We indicate below some of the major types of features in 2- or 3-dimensional images that have been used in the literature on application of pattern recognition (PR) techniques in image understanding and are possibly pertinent to our study. In the following paragraph, we briefly indicate the motivation that guided us in the choice of these features, and identify the nature of the constraints. The principal feature types derivable from an image will be discussed in section 2. Once the features are extracted, one must select a subset of this feature set that will retain the most useful information and remove any redundant and irrelevant information that may have a detrimental effect on the classifier performance. This is discussed in section 3. Section 4 provides a brief summary.

Excerpt: The GT200 is a fraudulent "remote substance detector" that is claimed by its manufacturer, UK-based Global Technical Ltd, to be able to detect from a distance various substances including explosives and drugs. The GT200 and its many iterations (Sniffex, ADE651, HEDD1) have been sold to a number of countries for a cost of up to 22,000 ($36,000) per unit, but the devices have been criticised as little more than a "divining rod" which lack any scientific explanation for why it should work. The device has come under scrutiny following revelations about the virtually identical ADE 651, another "substance detector" that has become the focus of a fraud investigation in the United Kingdom. The UK Government has banned the export of such devices to Iraq and Afghanistan in an order brought into force in January 2010 under the Export Control Act 2002 and has warned foreign governments that the GT200 and ADE 651 are "wholly ineffective" at detecting bombs and explosives. The Thai press has condemned the GT200 for having "given wrong readings on several occasions and even failed to detect explosive materials, resulting in the loss of life." Although Thai Prime Minister Abhisit Vejjajiva originally defended the devices, he later recanted when tests showed that they were completely ineffective at detecting explosives. They would still be used in...
