The booklet comprises lectures of a world NATO-Russian complicated study Workshop approximately Detection and Disposal of Improvised Explosives utilized by terrorists. The ARW used to be an occasion of a sequence of workshops prior to, facing detection of explosives by way of varied analytical tools and various form and compositions of the explosive cost. The formula ''Improvised Explosive'', IE, is a brand new expression for terrorist explosives, that have been produced commonly by way of an expert laymen in a home-made demeanour. IE should be any chemical compound or mix of advertisement elements, in a position to an explosive response after initiation by way of a detonating machine. The disposal of such IE is attached with a distinct threat, simply because IE are in lots of circumstances even more volatile and routinely extra delicate than advertisement or army explosives.

1 MeV and other lines for nitrogen). Detection of these secondary gamma-rays provides information about relative concentrations of carbon, oxygen and nitrogen in molecules of the inspected substance. V. I. OSETROV selectivity, since the method is sensitive to almost all elements constituting explosives; x one-side access to the inspected object. The main disadvantages are: x The method does not have spatial resolution, so if there are two objects close to each other, it will give their average chemical composition, which is related in an unknown way to the chemical composition of ES.
Time period, which is at disposal for detection. 4. IED Design IED design offers a broad range of possibilities, from mechanical alarmclock, battery and stick of dynamite to sophisticated initiation train and explosive charge masked as innocent component of checked object. Important aspect is the mass of explosive used. The range of explosive mass used in IEDs should be very different, starting with several grams in letter bombs and ending with the mass of several tons of explosive in a lorry on the other end of this range.
Secrecy of Inspection The main unmasking element of the inspection system is the matrix antenna. , and it can be covered from the front side by any dielectric material: plastic, cardboard, marble, granite etc. g. as an information or an advertising board. 3. Safety The power of the emitted EM radiation is determined by the distance, quality of the electronic channels, etc. Since no real focusing or EM waves is used, the density of the probing energy can be made very small – much smaller that that of a usual mobile phone.
