The detection of hidden explosives has become an issue of utmost importance in recent years. While terrorism is not new to the international community, recent terrorist attacks have raised the issue of detection of explosives and have generated a great demand for rapid, sensitive and reliable methods for detecting hidden explosives. Counterterrorist Detection Techniques of Explosives covers recent advances in this area of research including vapor and trace detection techniques (chemiluminescence, mass spectrometry, ion mobility spectrometry, electrochemical methods and micromechanical sensors, such as microcantilevers) and bulk detection techniques (neutron techniques, nuclear quadrupole resonance, x-ray diffraction imaging, millimeter-wave imaging, terahertz imaging and laser techniques). This book will be of interest to any scientists involved in the design and application of security screening technologies including new sensors and detecting devices which will prevent the smuggling of bombs and explosives. * Covers latest advances in vapor and trace detection techniques and bulk detection techniques * Reviews both current techniques and those in advanced stages of development * Techniques that are described in detail, including its principles of operation, as well as its applications in the detection of explosives

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.

Analytical Chemistry and Nano Sciences Applied to Detection of Explosives Explosive detection is defined as a non-destructive detection process used to determine if an area, product, or container contains any explosive material. Explosive material is anything that can be initiated to undergo very rapid decomposition resulting in the formation of more stable material, as well as the liberation of heat of the development of the sudden pressure effect. There are many different types of explosive detection that can be used in different fields. Explosive detection is extremely useful for many government agencies, and specifically for homeland security and other counter-terrorism organizations. Unfortunately, in the late 20th century there were many terrorist threats. Examples of these include threats on airplanes and to cities worldwide. The increase in threats led to new developments in the field of explosive detection.

ABSTRACT: Counter terrorism is the practice and technique that governments and militaries adopt to prevent terror threats. The illegal use of explosives has become a daily event in the modern world. For terrorist organization and insurgents, explosive devices have become a weapon of choice, which are being used to kill or harm civilians, military personnel and equipment/infrastructure. Hence, the detection of explosives is a paramount issue in security. Keeping this in mind, our group has developed an explosives detector. Our explosives detector can detect trace quantities of explosives on the surface of a baggage using the technique called differential reflectometry. This technique measures the optical absorption of energetic materials. These optical characteristics consist of characteristic shoulders between 370 nm and 490 nm; for example at 420 nm for Trinitrotoluene (TNT) and 480 nm for Triaminotrinitrobenzene. From our prototype, the differential reflectogram of these explosives has results at these characteristic shoulders. Our prototype was automated to increase the overall efficiency of the system.

Police officers on the beat, officers on patrol, all cops - local, state, tribal and federal, 750,000 strong - doing what they do every day are the first and most effective line of defense against terrorist acts committed in the Homeland. This manual is designed to overcome the failure of our national counter-terrorist strategy to better utilize local cops in homeland security by providing essential and practical knowledge local officers can use to identify terrorist precursor activities and more effectively interdict and prevent terrorist attacks from occurring. The goal is to acquaint officers with proactive “first preventer” knowledge and tactics so they can make police counterterrorism an integral part of their duties. Numerous case studies flesh out concepts such as terrorism, homeland security, terrorist threats posed by different terror groups, police counterterrorism intelligence, lone wolf terrorism, behavioral indicators of Islamist radicalization, terrorist tradecraft, terrorism indicators and warning signs, the terrorist attack cycle, terrorist attack tactics such as sniping, weapons of mass destruction, arson, improvised explosive devices (IEDs), suicide bombing tactics and surveillance detection techniques. This manual is an excellent source of basic to intermediate training for intelligence analysts, members of Joint Terrorism Task Forces, criminal intelligence investigators, and all police officers.

Traditionally, resources on terrorism and counterterrorism tend to focus on the social, behavioral, and legal aspects of the subject, with minimal emphasis on the scientific and technological aspects. Taking into account these practical considerations, the second edition of Science and Technology of Terrorism and Counterterrorism discusses the nature of terrorism and the materials used by terrorists. It describes how intelligence professionals and law enforcement personnel can detect and destroy these materials, and how they can deal with terrorist groups. This volume begins by introducing the shift in analysis of terrorist attacks after September 11, 2001 and summarizes selected case studies. It discusses the origin and nature of terrorism and the factors involved in diplomacy. Covering a broad range of topics, the book examines: Aerosol dispersion of toxic materials Bioterrorism and the manufacture, detection, and delivery of biological agents Agricultural terrorism Nuclear terrorism and nuclear weapons systems, threats, and safeguards Chemical terrorism, including manufacture, detection, delivery, and decontamination Cyber-terrorism Personal protective equipment The role of government at federal, state, and local levels The role of international agencies and their resources, capabilities, and responsibilities The National Infrastructure Protection Plan As terrorist activities increase globally, it is critical that those charged with protecting the public understand the myriad of ways in which terrorists operate. While we cannot predict where, when, and how terrorists will strike, our vigilance in staying abreast of the terrorist threat is the only way to have a fighting chance against those who seek to destroy our world.
