The ebook includes lectures of a world NATO-Russian complex study Workshop approximately Detection and Disposal of Improvised Explosives utilized by terrorists. The ARW was once an occasion of a sequence of workshops ahead of, facing detection of explosives by means of diverse analytical tools and diversified form and compositions of the explosive cost. The formula ''Improvised Explosive'', IE, is a brand new expression for terrorist explosives, which have been produced regularly through a professional laymen in a home-made demeanour. IE will be any chemical compound or mix of advertisement ingredients, able to an explosive response after initiation through a detonating equipment. The disposal of such IE is hooked up with a distinct hazard, simply because IE are in lots of circumstances even more volatile and routinely extra delicate than advertisement or army explosives.

Do technology and expertise create worth for society and the economic climate, and the way may well one move approximately measuring it? How will we overview its merits? do we also be definite that there are merits? Geisler argues that there are advantages, and they outweigh in worth the damaging affects that unavoidably accompany them.

In fact X-ray equipment is the most frequently used tool for detection of hidden IEDs in stabile checking points, the visualisation enables also the search of further contraband as weapons, and narcotics. The very important way of IEDs detection is the use of special trained dogs. The sensitivity of the dog nose is unique and electronic detectors have not yet overcome the dog detection ability. 33 H.

OVERVIEW OF DETECTION OF IE AND IED 21 At present the following “neutron in, gamma out” methods are used for detection of ES: 1. Thermal Neutron Analysis (TNA) 2. Fast Neutron Analysis (FNA) 3. Pulsed Fast Neutron Analysis (PFNA) 4. Pulsed Fast and Thermal Neutron Analysis (PFTNA) 5. Nanosecond Neutron Analysis/ Associated Particles Technique (NNA/APT). 1. Thermal Neutron Analysis (TNA) In TNA the object is irradiated by slow (thermal) neutrons, which produce gamma-rays in reactions of radiative capture with the nuclei of chemical elements constituting ES.
Scheme of the laser radiation transformation into a response signal. 56 54 S. BOBROVNIKOV It is convenient to measure the signal in the number of the recorded photo counts. Thus a laser delivering radiation of 1-W mean power emits about 1018 photons per second (ni in Diagram 1). Note, that the typical value of the absorption cross-section of most vapors in the near UV and visible ranges is ıx=10-20cm2. Let us take the concentration of the vapor to be at the level of cx = 107cm-3, or 1 ppt in relative units under standard atmospheric conditions.
