Introduction

Global changes in the late 20th and early 21st century contributed to an increasing threat of terrorism, organized crime and other security challenges, risks and threats, not only at national but also at international and even global security levels. Perhaps the greatest danger in this

respect is terrorism which requires security operators that confront it with g all available forces and means.

An important element to combat both terrorism and commando S operations is certainly counter-diversion protection. Counter-diversion protection is a technical discipline that basically involves finding, neutralization, transportation, deactivation and destruction of all types of explosive devices. Making all this possible to perform requires some technical assets for detection of the aforementioned devices with dangerous substances in their structure.

The use of hazardous materials in sabotage and terrorist activities

If we look back, we can see that the choice of the means to attack the target was following the development of science and technology and it developed in several historical phases: knife-poison, gun, dynamite, and, finally, bomb or explosive device. Nowadays terrorists primarily use technological achievements in the manufacture of improvised explosive devices in order to achieve their goals. By using hazardous materials, terrorists can disable or kill a large number of people either in the civilian or military sector, and cause panic and fear thus undermining the security of the state.

It is obvious that hazardous materials are closely related to sabotage - terrorist activities. There is almost no sabotage or terrorist action without some of hazardous materials. But what are hazardous materials?

According to the Law on Safety and Health at Work, hazardous .§ materials are explosive, flammable, oxidizing, poisonous, repulsive, H contagious, corrosive, carcinogenic and radioactive substances, o established by standards and other law regulations, produced, used or stored in the work process, and also materials that have such characteristic, when attached to a certain substance are dangerous to life and health of employees (Sluzbeni glasnik RS, 101/2005), (Sluzbeni glasnik RS, 91/2015).

According to another definition, hazardous materials include chemical compounds, mixtures of chemical compounds or chemical elements which have a dangerous (harmful) characteristic such as explosion, flammability, radioactivity, or other toxicity (Postic et al, 1998). Hazardous materials can be classified on the basis of different criteria, but based on the hazardous effects manifested, they are divided into the following four groups: - explosive,

- flammable substances,

- radioactive substances, and

- toxic materials.

By studying the characteristics of hazardous materials, it is easy to conclude that they are all very suitable for use in sabotage - terrorist purposes for which we have a lot of evidence in current events in the world. There is a real risk that protagonists of international terrorism in the future will use nuclear, biological, chemical agents more and more, and those most widely used will be dangerous substances of high toxicity, high volatility, simple to use, and difficult to detect (industrial substances, toxic chemical substances, etc.). Hazardous materials are easily available on the market and they can be easily synthesized using information from the Internet, which makes terrorists' job much easier.

It is clear that their use is detrimental to people and material and technical resources, so the knowledge about them and modern equipment for their timely detection are the basic preconditions for the prevention of such scenarios and fight against them in case they occur.

Devices for the detection of hazardous materials and fuzes - initial components of devices

When analyzing sabotage and terrorist activities today, it can be concluded that special attention must be paid to preventive measures. Consequently, anti-terrorist measures and actions are imposed as necessary preventive actions, or actions that prevent the execution of terrorist attacks using hazardous materials and their harmful consequences for the safety of people and property. Also, modern methods are applied as well as technical developments which detect terrorists with their materials and resources used to achieve their goals. From this stems the importance and role of modern assets of detection in counterdiverson protection.

Detection is closely related to security screening. Various detection devices are used for that purpose. These devices can be divided into:

- devices for the detection of hazardous materials, and

- devices for detection of fuzes - initial components of devices.

Devices for the detection of hazardous materials can be classified as follows:

- devices for explosives detection,

- devices for the detection of flammable substances,

- devices for the detection of radioactive substances, and g

- devices for the detection of toxic substances. ^

The following devices are used for detecting fuzes - initial & components:

- metal detectors,

- X-ray apparatus, and

- stethoscopes.

Each of these devices uses certain methods of work, which will not £

be discussed in detail on this occasion. We will try to show here some of the advanced representatives of each of the mentioned groups of devices.

One of the representatives is a handheld explosives detector E3500 Chemilux. This is a handheld device which works on the principle of chemiluminescence and its purpose is detection of explosives. It is one of the first such devices in the world (Figure 1). It detects military, industrial, and even hand-made explosives, liquid, powder, plastic, nitrate, black powder, and more. It has a dual mode of particles and vapor, and is characterized by a very fast detection (up to 16 seconds) and accurate detection results. The device detects particles and vapors of explosives in a non-invasive way in luggage, letters, vehicles, clothing, electronic devices, documents, etc. It is resistant to various weather and soil conditions, simple to use (one button), with an LCD display with status messages, red and green LED lights, and optional headphones for the audio signal. Data from the device can be forwarded via Wi-Fi. It is powered by a 12V battery whose life is about 6 hours. It weighs about 2.7 kg. No isotopes, radioactive sources, and no license are required. It is suitable for police and military units, customs, ports, airports, bus and railway stations, nuclear facilities, embassies, etc. (Autoclear, 2013)

Explosives detection devices

When it comes to devices for explosives detection, contemporary devices are able to simultaneously detect explosives and narcotics. All these devices are reliable, fast, flexible, and safe to handle. Some of the leading companies in this field are American FLIR Systems (Forward Looking Infrared), Syagen Technology Inc, SEDET (Sociedad Europea <8 de Deteccion S.L.) in Europe LDS (Laser-Detect system) in Israel, etc.

The Fido NXT is a hand-held wand which uses the method of molecular spectroscopy, and the principle on which it works is amplifying fluorescent polymers (AFP - amplifying fluorescent polymers). The sensor is made of a capillary glass tube whose interior is covered with a polymer film. It is a product of the famous company FLIR Systems, Inc (Figure 2). Its dimensions are 368.3 x 114.3 x 69.9 mm, and it weighs only 1.4 kg. A lithium battery used to provide power ensures the autonomy of 8 hours. It has a USB port and the MS Office operating system for storing data. It can operate at temperatures ranging from -10 ° to + 55 ° C.

It detects TNT (trinitrotoluene), DNT (dinitrotoulen), Semtex, C4, RDX (Research Department explosive or Royal Demolition explosive or simply hexogen), PETN (pentaerythritol tetranitrate), powder explosive, some industrial explosives, improvised materials, but not peroxides. The start-up time is about 5 minutes and the detection time about 10 seconds. (Laurus systems, 2019)

Devices for the detection of flammable substances

When it comes to flammable materials, it should be noted that combustible gases and vapors are particularly dangerous. Any type of gas or vapor reacts explosively under certain temperature and pressure determined by the lower explosive limit (LEL) and the upper explosive limit (UEL). Risks are reduced by a permanent control of these limits. There are two types of devices for the detection of flammable vapors, gases and particles, those that detect a specific gas and those that detect several gases. Explosive/flammable ones are hydrogen (H2), a natural gas/methane (CH4 propane - butane, isopropyl alcohol, hexane (C6H14), octane fuel, acetylene (C2H2), ethylene (C2H4), ammonia (NH3), butanone, ethanol (C2H5OH ), methanol (CH3OH), toluene, pentane (C6H12), ethylene - oxide (C2H40), (Spectra, 2019). One of the newest representatives of devices for the detection of these substances is a PS200 Series from the Gas Measurement Instruments Ltd company. This sturdy and accurate portable gas detector provides unparalelled protection in the closed space with the audio and visual alarm in case of exposure to gases or combustible substances. It detects up to 4 types of gases simultaneously. It can be configured to detect methane, oxygen, carbon monoxide, hydrogen sulfide, and other flammable gases (Figure 3).

In the case of the aforementioned gases, there is a sound, light and vibration alarm (GMI, 2019).

Apparatus for the detection of radiation

The operation of the majority of radiation detectors is based on a ionization chamber. The radiological detector RadSeeker is a handheld, portable, rugged and highly accurate detector and an identifier of radioisotopes detected by gamma and neutron radiation. Easy to use, it provides fast, simple, and specific information for risk assessment. It is suitable for customs control, border protection, emergency response, and radiological control of objects and persons (Figure 4).

The detector can be used for searching or "screening" to detect radioactive sources, and then to clearly identify whether the detected radioactive material is harmless natural radiation or a more dangerous source, such as special nuclear materials or those contained in 'dirty bombs'. For each source identified, the detector provides risk assessment and describes the source as harmless or as a threat, so that there is no need for the operator to guess.

Figure 4 - Radiological detector RadSeeker Рис. 4 - Радиологической детектор RadSeeker Слика 4 - Радиолошки детектор RadSeeker

The built-in wireless capabilities, including Wi-Fi and satellite telephone interface, give those in the remote command center an easy access to information such as identified threats and the location of the device/operator.

In situations when it is considered unsafe to send an operator to the location, the detector can be set mechanically, and monitoring and device control can be performed from a safe distance. It is equipped with three types of alarms (visual, light and vibration) as well as with a GPS (Smiths detection, 2019a). The technical characteristics of the device are given in Table 1.

Devices for the detection of toxic substances

The monitor of chemical agents - CAM (Chemical Agent Monitor) is a manual transmission asset, designed for the detection of nerve toxic substances and blister agents in the air (point monitor), for rapid determination of the boundaries of the contaminated area, for detecting contamination of people, ships, planes, motor vehicles, buildings and facilities, for checking the performance of decontamination works, and for monitoring the situation in the objects of collective protection (Figure 5).

The CAM detects nerve and blister agents in the form of vapor in the lowest concentrations that may affect people in a short period. The lowest concentration for nerve agents is G>0.03 mg/m3 per minute and for V>0.01 mg/m3 per minute. For blister agents, the lowest concentration is H>0.01 mg/m3 per minute. It can also detect chlorine, phosgene and hydrogen cyanide (HCN) in the PLUS configuration mode. It contains a beta radiation source of Ni-63 (10 mCi). It works with one battery whose durability depends on temperature (normally 12 hours at a temperature of about 20°C). The basic features of the monitor are:

The portable walk-through metal detector Fisher M-SCOPE (Figure 8) provides maximum protection of objects and events in places where there are no static detectors installed. The entire unit weighs only about 38 kg and it can be assembled or disassembled by one person in about 5 minutes. The M-SCOPE has three detection zones with LED indicators which extend from the bottom to the top of the device as well as the signal strength indicator which allows easy assessment of the situation, and a greater flow of persons. By using a simple control interface to the display, the operator can select one of 100 different levels of sensitivity. Rechargeable batteries provide approximately 40 hours of continuous operation. Ruggedized electronics and shock-resistant materials used in the casing guarantee long life even in the most severe working conditions (Fisherlab, 2016).

Conclusion £

CO CM

CO !± CP

Terrorism is the biggest threat to the security of the international community. The methods and means used for such purposes are on higher and higher technical, technological and efficiency levels, and their impact is steadily increasing. Victims are not only individuals, but a much wider circle of people and even states themselves.

In an attempt to locate, neutralize, transport, deactivate and destruct all types of devices used by terrorists and saboteurs, security forces use modern assets. Due to the complexity and sophistication of modern 8 assets used in counter-diverson protection, the key necessity is their understanding and knowledge of their use. We must also take into j? account technical - technological advances in science and in means used by terrorists and saboteurs to achieve their goals.

In addition to the knowledge and use, it is necessary to constantly monitor the development and procurement of new devices and equipment for detection, identification and neutralization of dangerous devices used by terrorist and saboteurs, in order to effectively counteract modern security challenges, risks and threats.

To be able to successfully oppose to terrorism and other forms of security threats, members of security services need to learn and improve on a daily basis. In that sense, perhaps the best teacher is practice. In their work, members of counter diversion units use experiences from their own practice as well as those from related services in the world, thus improving their performance and efficiency as well as counter-terrorist measures in general.

In a conversation with the members of military police and the Police 1 Brigade counter diversion units, it is possible to hear a number of cases 5 which show the effectiveness of modern assets for detection as well as the skills of their use, but due to the sensitivity of the subject matter, it will not be elaborated further on here.
