The axiom about the potential dangers of man-made factors
Axiom about the potential dangers of activity – the fundamental postulate is the basis for scientific problems of human security.
Protection against man-made hazards is achieved by improvement of hazards sources.
Any technical system is potentially dangerous.
The technological hazards exist if the daily activity associated with the flows of matter, energy and information in the technosphere exceed thresholds.
The source of man-made hazards are elements of the technosphere.
Technological hazards are localized in space and time.
Technological hazards have a negative effect on people, the environment and elements of the technosphere simultaneously.
Technological hazards impair human health, lead to personal injury, economic loss, and degradation of the environment.
2. Classification of highly toxic substances (HTS)
All harmful substances on the degree of their effect on yhe human are devided into 1-extremely dangerous 2-high-risk 3-moderately dangerous 4-low-hazard
If the air contains a harmful substance, its concentration should not exceed the maximum admissible concentration - milligrams af a harmful substance/1 cubic meter of air.
3. Maximum permissible concentrations, emissions, exposure levels 3) Maximum permissible concentrations, emissions, level of exposure
The maximum permissible concentration (MPC) of hazardous substances in the environment is
defined as the maximum concentration of pollutants in the environment, assigned to a particular
averaging period and the periodic exposure or throughout life, which does not cause harmful impact
on humans and the environment in general.
Standards of MACs are uniform throughout the Republic of Kazakhstan and developed by the
Ministry of Health. In setting standards MPC takes into account two types of indicators of pollution
of nature - the maximum one-time maximum allowable concentration and the daily maximum
allowable concentration. The first determines the degree of a short exposure to harmful substances
on the normal functioning of the human body. Second - the acceptable level of pollution, which in
the longer term effects on the human organism does not cause changes in the state of human health.
4. Physical hazards and their characteristics
Hazards. According to the official standards dangers are divided into:
Physical – moving machinery, elevated levels of pollution and the dust in the work area.
The permissible levels of harmful substances
The Maximum permissible levels (MPL) of noise, vibration, magnetic fields and other adverse physical effects are developed and established by the health authorities of the republic and are measured in decibels. Normal household noise allowed in the 20 decibels, soreness in humans appears with the noise of 90 decibels.
The maximum permissible level of radiation for magnetic fields, electromagnetic radiation, radiation are developed by the Ministry of Health and is measured in micro-roentgen per hour.
The magnetic fields, electromagnetic radiation, radiation exposure also adversely affect the health and the environment. These standards are developed by the Ministry of Health and are measured in micro-roentgen per hour. Division of Radiation Safety of the Ministry of Environment and Natural Resources (ENR) monitors two areas: natural radiation, that is, and terrestrial radiation and artificial radiation, as a result of human activity.
Partly a matter of normalization of the maximum permissible level of radiation is provided in the Law of the Republic of Kazakhstan "On the use of atmospheric energy", adopted on 14 April 1997 and the Law "On radiation safety".
The maximum permissible levels (MPL) of chemical use in agriculture – maximum norm for agrochemicals in agriculture and forestry determined with regard to pesticides, mineral fertilizers, chemical protection and stimulates plant growth.
6. Environmental Passport of an industrial enterprise. Environmental Passport of an enterprise is a standard - technical document that includes data on the use of resources by company, expressed through a system of indicators, and on detection of its impacts on the environment.
The basis for development of ecological passports are key indicators of production, the resolution on the nature management, passports for gas and water treatment plants and installation of recycling and waste management, forms of state statistical reports and other documents.
In accordance with applicable law, the company must evaluate their efforts to use natural resources and the impact on the environment, planning and implementation of environmental activities under the control of local administration bodies and Ministry of Natural Resources.
Environmental Passport is developed by an enterprise at the expense of its funds and by the manager of the company in consultation with local authorities and the territorial authority of Ministry of Natural Resources, where it is registered.
7. Environmental Assessment. Basic principles of the environmental impact assessment.
Environmental Assessment. Basic principles of the environmental impact assessment.
Another function of the state management in the field of ecology is to conduct environmental impact assessment. In the existing legislation organization and legal regulation of environmental impact assessment is highlighted in the chapter 11 of the Law "On Environmental Protection" (now Ecological Code), and 18 March 1997 adopted the Law "On Environmental Assessment".
This law regulates social relations in the field of environmental assessment in order to prevent the negative impact of administrative, economic and other activities on the environment, life and health of the population of the Republic of Kazakhstan. In this Law the environmental assessment is defined as a confirmation that the planned economic and other activities correspond to environmental requirements and determination of the admissibility of the object to implement environmental assessment in order to prevent possible adverse impact of
the activity on the environment and associated social, economic and other consequences of the
implementation of the object of environmental examination. Basic principles of environmental impact assessment:
• presumption of potential environmental danger of any economic or other activities;
• mandatory of state environmental assessment before making decisions on the
implementation of the object of environmental expertise;
• the complexity of assessing the impact of economic and other activities on the
environment;
• independent experts of environmental expertise in carrying out their responsibilities;
• scientific validity, objectivity and legitimacy of the conclusions of environmental impact
assessment;
• transparency, participation of public organizations (associations), responsiveness to public
opinion;
• responsibility of parties for environmental impact assessment for its quality.
8. The Law of the RK "On Ecological Assessment ". Two types of environmental impact assessment
The RK Law "On Environmental Assessment" gives them the following rights:
• create eco-expert commissions and groups and other groups, to involve qualified local and
foreign experts and scholars, legal entities on a contractual basis;
• oversee the work of expert units;
• lead the advice of environmental expertise, organize their activities;
• Identify methods of examination;
• sign an ecological expertise;
• request additional materials needed for the examination;
• reject given the environmental review materials that do not meet the necessary standards
and regulations;
• other powers in accordance with the law.
The RK Law "On Environmental Assessment" defines 2 types of environmental impact
assessment:
1. State environmental assessment - view of the central executive body of the Republic of
Kazakhstan in the sphere of environmental protection and its field offices.
2. Public environmental assessment - an activity undertaken on a voluntary basis by expert
commissions established at the initiative of individual groups, associations and research
organizations for the environmental assessment of any activity. It can operate independently of the
holding for the same projects of the state ecological expertise.
9. Highly toxic substances (HTS). Application of HTS. Effects of HTS. Highly toxic substances (HTS) - are chemical substances that are intended for use in the
economy and have a toxicity that can cause massive destruction of people, animals and plants.
At several sites of the national economy the production, use, storage and transportation of HTS takes place. Violation of technology of their production, storage and transportation, lack of discipline among staff are responsible for the creation of emergencies, disasters, leading to tragic consequences. Accidents with pollution may occur as a result of destruction of the economic facilities in the wartime or acts of sabotage, to the same results could lead earthquakes, floods, landslides, fires, and other natural disasters.
When poured out (emissions) HTS form lesions. A lesion of HTS is called an area, within which there were massive destruction people, farm animals and plants by HTS. Moreover, during the hostilities or natural disasters occurring at the site of manufacture, use or transporting of HTS, the probability of these lesions is greatly increased. They are usually divided into areas of direct pouring out (discharge) of HTS, and zones of localization of their vapors.
An important feature of the lesions formed by the HTS is the duration of the presence of areas of direct pouring out (discharge) of substances, ie persistence of infection. Most of the HTS having a boiling point up to 20 C (chlorine, hydrogen sulfide, ammonia) tend to evaporate quickly, so the resistance of infection in areas where they are pouring out (discharge) is small. However, vapor of such substances, including hazardous concentrations can be detected at large distances (up to several kilometers) from where they were poured out (discharged).
Zone of infection is called sites contaminated with highly toxic substances.
The destructive effect of HTS appears as a result of entering onto human skin as well as by
inhalation of vapors.
ffect of HTS on human health
Acute intoxication occurs, as a rule, suddenly after a brief exposure to relatively high concentrations of venom and is expressed more or less severe and specific clinical symptoms. In production conditions acute poisonings are most commonly associated with the accident, malfunction of equipment or with the introduction in technology of new materials with little-known toxicity.
Chronic intoxication caused by the intake of small amounts of venom and associated with the development of pathological phenomena only under condition of the long-term exposure, sometimes by several years.
10. Lesions. Classification based on the degree of human exposure to HTS. Chemical harmful factors on the nature of their affect on human organism are divided into the following subgroups: general toxic, irritating, sensitizing (causing allergies), carcinogenic (causing the development of tumors), mutagenic (acting on germ cells of the body).
This group includes many fumes and gases: fumes of benzene and toluene, carbon monoxide, sulfur dioxide, nitrogen oxides, aerosols of lead, etc., toxic dusts produced, for instance, when cutting beryllium, lead bronze and brass and some plastics with harmful fillers.
This group includes aggressive liquids (acids, alkalis), which can cause chemical burns of the skin in contact with them. The exposure levels of workers to harmful factors are normalized by the maximum permissible level, whose values are specified in the appropriate standards of safety standards and sanitary rules.
Harmful substance (industrial poison), entering the human body during his professional activities, causes pathological changes.
The main sources of air pollution of industrial premises by harmful substances can be raw materials, components and finished products. Diseases arising from the impact of these substances are called occupational poisoning (intoxication).
11. Effect of contaminants on human health (acute and chronic intoxication).
Prevention of occupational poisoning
12. Characteristics of hazardous substances used in production (ammonia, chlorine etc.). Actions in case of accidents. Ammonia: MAIN PROPERTIES: Colorless gas with a sharp suffocating odor, the boiling point of -33.4 C, vapor is lighter than air, explosive when mixed with oxygen. Ammonia is unstable, high-speed. Infected cloud is distributed in the upper atmosphere. FIRST AID MEASURES: First aid in the focus of the lesion, carried out in order of self-and mutual-aid: Wash eyes and face with water, wear a mask or cotton-gauze bandage moistened with a 5% solution of citric acid, and wash exposed skin with water, immediately leave the center of contamination
CHLORINE: KEY FEATURES: Greenish-yellow gas with a sharp odor, the boiling point of 34.1 C, vapor is heavier than air. FIRST AID MEASURES: First aid in the focus of the lesion, carried out in order of self-and mutual-aid: Rinse face with water, wear a mask or cotton-gauze bandage soaked in 2% solution of baked soda, wash exposed skip with water and soup, immediately leave the center of contamination.
Hydrochloric acid: KEY FEATURES: A colorless liquid with a sharp odor. It is easy to evaporate and smokes in the air. Is readily soluble in water. Corrosion for most metals. Boiling point 110 C, vapor is heavier than air. FIRST AID MEASURES: First aid in the focus of the lesion, carried out in order of self-and mutual-aid: Rinse face with water, wear a mask or cotton-gauze bandage soaked in 2% solution of baking soda, and exposed skin with soap and water, leave immediately lesion.
Other Toxic Substances: Methane, Oxygen. Acetylene, Propane-butane mixture, Methanol (methyl alcohol, carbanol), Diethylene glycol, Odorant, Gas condensate
13. The concept of bacteriological (biological) weapons (BW). "Weapons of mass destruction" (WMD) have been defined as nuclear, biological and chemical weapons (NBC) employed for the purpose of inflicting massive damage, including the killing of large numbers of civilians.1 The term consolidates nuclear, biological and chemical weapons into one category because, despite differences in their effects and use, they share enormous lethality and symbolism. WMD is an open-ended concept, potentially allowing for the development of other technologies of mass destruction. "Mass Destruction" is a relative term. BW contains living organisms (as well as the means of their delivery) which is intended for use in warfare to cause death or disease and which for its effect depends on the ability to multiply in the person, animal or plant attacked, while toxins are poisonous products of organisms, which unlike biological agents are inanimate and not capable of reproducing themselves.6 Typically, a BW uses micro-organisms (i.e., bacteria or viruses) or toxins. While bacteria are single celled organisms that invade the human body, replicate and cause disease and death, viruses do the same, but are much smaller, consist of genetic material (DNA or RNA) and must invade a host cell to multiply, Poisonous substances that can be synthetically produced or derived from living organisms are toxins.
14. Types and basic properties of BW (bacteria, viruses, rickets, fungi). 14. Types and basic properties of BW (bacteria, viruses, rickets, fungi).
Types and basic properties of biological agents
Pathogenic microorganisms are causative agents of infectious diseases in humans and animals,
which, depending on the size of their structure and biological properties, are divided into the
following classes: bacteria, viruses, fungi, spirochetes and protozoa. The last two classes of
microorganisms are of no importance as biological weapons of destruction.
Bacteria - single-celled microorganisms which are very diverse in their forms. The main forms of
bacteria are: staphylococci, diplococcus, streptococcus, bacillus, vibrions, spirillum.
Their sizes varies from 0,5 up to 8-10 microns. Bacteria in the vegetative form, ie in the form of
growth and development are very sensitive to heat, sunlight, large fluctuations in moisture and
disinfectants and, conversely, retain sufficient stability at low temperatures, even up to minus 15-25oC. Some types of bacteria survive in adverse conditions form the protective capsule or spore.
Microbes in the spore form are highly resistant to desiccation, lack of nutrients, high and low
temperatures and disinfectants. The pathogenic bacteria such as anthrax, botulism, tetanus, etc. have the ability to form spores.
According to the literature, almost all species of bacteria used as weapons of destruction, relatively easy to grow in artificial media, and their mass production is possible using equipment and processes used in industry in the manufacture of antibiotics, vitamins, and products of modern fermentation industries. The majority of agents responsible for the most dangerous human diseases such as plague, cholera, anthrax, glanders, meliodiosis etc. belong to the class of bacteria.
Viruses – an extensive group of microorganisms with a size from 0,08 to 0,35 micron. They can live and reproduce only in living cells by using the biosynthetic machinery of the host cell, i.e. are intracellular parasites. Viruses have a relatively high resistance to low temperatures and desiccation. Sunlight, particularly ultraviolet rays, as well as the temperature above 60oC and disinfectants (formalin, chloramine, and others) are destructive for viruses. Viruses are responsible for more than
75 human diseases, among which are highly dangerous such as smallpox, yellow fever, etc.
Rickettsiae - a group of microorganisms, which occupies an intermediate position between bacteria and viruses. Their sizes - from 0,3 to 0,5 microns. Rickettsiae do not form spores, resistant to drying, freezing and fluctuations in relative humidity, but are sensitive to high temperatures and disinfectants. Diseases caused by rickettsia, called rekketsioses among them are highly dangerous, such as typhus, spotted fever of Rocky Mountains, etc. In vivo rekketsioses are transmitted to humans mainly through the blood-sucking arthropods, which the infectious agents inhabit often as harmless parasites.
Fungi - one- or multi-cellular organisms of vegetable origin. Their sizes varies from 3 to 50 microns or more. Fungi can form spores, are highly resistant to freezing, drying, sunlight and disinfectants.
Diseases caused by pathogenic fungi are called mycoses. Among them are such serious infectious diseases in human like koktsidioadomikos, blaotomikos, histiplasmosis, and others.
15. Diseases caused by biological agents and toxins (anthrax, meliodiosis, glanders, botulism). Pathogenic microorganisms are causative agents of infectious diseases in humans and animals, which, depending on the size of their structure and biological properties, are divided into the following classes: bacteria, viruses, fungi, spirochetes and protozoa. The last two classes of microorganisms are of no importance as biological weapons of destruction
Anthrax
Anthrax – is general acute infectious disease of domestic animals and humans. The disease in humans is characterized by high temperature and the formation of specific carbuncles on the skin and mucous membranes, or the development of inflammatory changes in the lungs or intestine with symptoms of bleeding.
Meliodiosis – is an infectious diseases of humans and rodents, similar to glanders. The causative agent, for the similarity with the bacterium glanders is called false glanders. The microbe – is a thin bacillus, which does not form spores, has the mobility due to the presence of the beam flagella at one end, it is resistant to drying, remains viable at temperatures 26-28 degrees in soil up to a month, in the water - more than 40 days. It is sensitive to disinfectants and heat - under their influence it dies within minutes.
Glanders
Glanders is a chronic disease of horses, rarely of camels, cats and people, caused by the bacteria of glanders. Symptoms: specific nodes, and then ulcers in the respiratory organs and skin. Infection occurs through contact with sick animals. Infected animals should be destroyed. In our country, glanders has been eradicated long ago, but there is a danger of its use as biological weapons.
Botulism
Botulism is caused by botulinum toxin, which is one of the most powerful poisons known at present. Infection can occur through the respiratory tract, gastrointestinal tract, broken skin and mucous membranes. The incubation period-from 2 hours to few days.
Botulinum toxin affects the central nervous system, vagus nerve and nervous apparatus of the heart;
Preventive measures at the sign of use of bacteriological agents.
Preventive measures
Pathogens can enter the human body in various ways: by inhalation of contaminated air, when eating contaminated food and water, by ingestion of microbes into the bloodstream through open wounds and burns of the surface, from bites of infected insect and at contact with sick people, animals, infected objects not the use of just at the time of bacterial (biological) agents, but also long after their application, if sanitation of the personnel was not carried out. The common symptoms of many infectious diseases are high body temperature and a significant weakness, as well as the rapid dissemination, resulting in a focal hearth of diseases and poisoning. Successful defense against biological weapons depends also on the degree of population immunity to infectious diseases and toxins. Immunity can be achieved above all by the general strengthening of the body by systematic hardening and physical education and sports, even in peacetime, these measures should be the rule for the entire population.
Personnel located in the hearth of bacteriological (biological) infection should not only timely and correctly use protective equipment, but strictly comply with the rules of personal hygiene
17. Rules of conduct and actions of people at the foci of bacteriological destruction 17.Rules of conduct and actions of people at the foci of bacteriological destruction
Timely and effective measures to protect against bacterial agents, is largely determined by how well the signs of bacteriological attack of the enemy are studied.
At finding at least one of the signs of biological weapons by the enemy, you must immediately put on a mask (respirator, tissue dust mask or cotton-gauze bandage), if possible, and skin care products and to notify the nearest administrative body of the CD or medical facility. Then, depending on the situation you can hide in the protective structure (asylum, anti-radiation or simple shelter). Timely and proper use of personal protective equipment and protective structures prevent from getting bacterial agents in the respiratory system, on the skin and clothing.
In order to ensure effective protection against biological weapons of great importance are the epidemiological and sanitary-hygienic measures. It is necessary strict adherence to the rules of personal hygiene and sanitation requirements, ensuring food and water supply. Cooking and eating have to exclude the possibility of bacterial contamination means; various kinds of utensils used for cooking and eating, should be washed with disinfectant solutions or treated with boiling.
The hearth of bacteriological lesion is called the city, other towns, the objects of national economy
and the territories contaminated with bacterial agents and the sources of the spread of infectious
diseases.The simultaneous appearance in the case of biological weapons a large number of infectious diseases in humans may have a strong psychological impact, even in healthy people. The action and behavior of every person in this case should be aimed at preventing possible panic
18. The measures of prevention: Quarantine and observation. Disinfection and disinsection
Quarantine and observation can be applied to prevent the spread of infectious diseases in the application of bacteriological weapons, by the order of the chiefs of the CD of districts and cities, and the objects of the national economy.
Quarantine is introduced with establishing the incontrovertible facts of the use of bacteriological weapons by the enemy, and mainly in cases of the use of particularly dangerous pathogens. Quarantine regime provides complete isolation of the lesion from the surrounding population and is intended to prevent the spread of infectious diseases.
Disinfection is aimed at decontamination of environmental objects, which are necessary for normal operation and safe location of people. Disinfection, for example, of areas, facilities, equipment, machinery and various items can be carried out using fire, agriculture, construction and other equipment.
Disinsection and rodent extermination, which are known to be carriers of infectious diseases. To kill insects physical (boiling, ironing a heated iron, etc.), chemical (application of desinsective means) and combined methods are used; extermination of rodents in most cases is carried out with the help of mechanical devices (traps of various types) and chemicals.
19. Methods and means of application of bacterial agents.
Pathogenic microorganisms are causative agents of infectious diseases in humans and animals, which, depending on the size of their structure and biological properties, are divided into the following classes: bacteria, viruses, fungi, spirochetes and protozoa.
Bacteria - single-celled microorganisms which are very diverse in their forms. The main forms of bacteria are: staphylococci, diplococcus, streptococcus, bacillus, vibrions, spirillum.According to the literature, almost all species of bacteria used as weapons of destruction, relatively easy to grow in artificial media, and their mass production is possible using equipment and processes used in industry in the manufacture of antibiotics, vitamins, and products of modern fermentation industries.
Viruses – an extensive group of microorganisms with a size from 0,08 to 0,35 micron.
Rickettsiae - a group of microorganisms, which occupies an intermediate position between bacteria and viruses. Their sizes - from 0,3 to 0,5 microns.
Fungi - one- or multi-cellular organisms of vegetable origin. Their sizes varies from 3 to 50 microns or more.
example. Chronic meliodiosis The use of this disease may be different: the use of microbial cultures in bombs, projectiles, spray tank, spray gives different results. Also meliodiosis can be used for subversive detachment for contamination of air supply, water sources, storage of food. Protection against the disease in case of its application as a biological weapon may be wearing the protective clothing, gear, gas masks in the infected zone and compulsory disinfection of food and water. To present the spread of the disease the armament, equipment used in the areas of infection, should be disinfected and contaminated land – deratisated (treated against rats).
20. BW facilities developed on the territory of the Kazakhstan for the open-air testing and production of BW agents
20) Bacteriological (biological) weapons - are special munitions and military equipment with delivery
means, filled with bacterial (biological) agents. Bacteriological (biological) weapons are means of
mass destruction of people, animals and agricultural crops.
The history began in 1920, finished on 7 May 2007
On 17 April, Kazakhstan's government ratified the Convention on the prohibition of the
development, production and stockpiling of bacteriological and toxin weapons and on their
destruction. President Nursultan Nazarbayev signed the legislation on 7 May 2007. Kazakhstan
joining the Convention will mark yet another step toward strengthening its role as an advocate for
the nonproliferation of WMD.
21. The Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on their Destruction (10 April 1972). The States Parties to this Convention, Determined to act with a view to achieving effective progress towards general and complete disarmament, including the prohibition and elimination of all types of weapons of mass destruction, and convinced that the prohibition of the development, production and stockpiling of chemical and bacteriological (biological) weapons and their elimination, through effective measures, will facilitate the achievement of general and complete disarmament under strict and effective international control. Recognizing the important significance of the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases and of Bacteriological Methods of Warfare, signed at Geneva on 17 June 1925, and conscious also of the contribution which the said Protocol has already made, and continues to make, to mitigating the horrors of war. Recognizing that an agreement on the prohibition of bacteriological (biological) and toxin weapons represents a first possible step towards the achievement of agreement on effective measures also for the prohibition of the development, production and stockpiling of chemical weapons, and determined to continue negotiations to that end. This convention consists of several article with responsibilities of States Parties.
Protocol for the Prohibition of the Use in war of asphyxiating, poisonous or other Gases and of Bacteriological Methods of Warfare (Geneva, 17 June 1925).
22.Geneva, 17 June 1925
Protocol for the Prohibition of the Use in war of asphyxiating, poisonous or other
Gases and of Bacteriological Methods of Warfare.
The undersigned are authorized on behalf of their respective Governments:
Considering that the use in war of asphyxiating, poisonous or other gases, as well as all analogous liquids, materials and processes, has been justly condemned by public opinion of the civilized world;
Considering that the prohibition of this application was formulated in the treaties, the participants in which are the majority of the world’s governments;
to be universally accepted as the logged in international law, this prohibition, binding both the conscience and practice of nations;
state:
that the High Contracting Parties, since they are not already parties to the treaties prohibiting this use, accept this prohibition, agree to extend the ban on bacteriological warfare equipment and agree to be bound to each other by provision of this Declaration.
The High Contracting Parties will exert every effort to induce other States to accede to this Protocol. This accession will be notified by the Government of the French Republic, and the last - all signatory and acceding states. It would come into effect from the date of notification by the Government of the French Republic.
This Protocol, French and English texts will be considered authentic, shall be ratified as soon as possible. It will be the date of this day.
Ratification of the Protocol will be forwarded to the Government of the French Republic, which shall notify each signatory and acceding power of acceptance of such deposit.
Instruments of ratification or accession are deposited in the archives of the Government of the French Republic.
This Protocol shall enter into force for each signatory state since ratification, and from that moment such state will be linked to other states, have already carried out the delivery of their ratifications.
In witness whereof the Plenipotentiaries have signed this Protocol. Done at Geneva in a single copy on seventeen day of June one thousand nine hundred and twenty-five.
23. General characteristics of nuclear and radiological weapon s A weapon of mass destruction (WMD) is a weapon that can kill and bring significant harm to a large number of humans (and other life forms) and/or cause great damage to man-made structures (e.g. buildings), natural structures (e.g. mountains), or the biosphere in general.
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter. The first fission ("atomic") bomb test released the same amount of energy as approximately 20,000 tons of TNT. The first thermonuclear ("hydrogen") bomb test released the same amount of energy as approximately 10,000,000 tons of TNT.
A radiological weapon or radiological dispersion device (RDD) is any weapon that is designed to spread radioactive with the intent to kill and cause disruption.
One version, known as a dirty bomb, is not a true nuclear weapon and does not yield the same explosive power. It uses conventional to spread radioactive material, most commonly the spent fuels from nuclear power plants or radioactive medical waste.
Radiological weapons of mass destruction have been suggested as a possible weapon of terrorism used to create panic and casualties in densely populated areas. They could also render a great deal of property useless for an extended period, unless costly remediation was undertaken. The radiological source and quality greatly impacts the effectiveness of a radiological weapon.
