The Russia-Ukraine war is intensifying with each passing day, and its devastating effects are unfolding on daily basis, including mass migration and civilian casualties. This is causing a great rift between the major powers and the world is at the brink of a huge catastrophe.
The possibility of a nuclear devastation is on the line.
During the past few days, there are certain terms being frequently used by the major powers against each other, i.e. accusations of using weapons of mass destruction.
Russian media accused Ukraine for building a plutonium-based “dirty bomb”, the Ukrainian ambassador to the US accused Russia for using thermobaric or “vacuum bomb”, Russian foreign ministry spokesperson accused the US for supporting a bioweapons programme in Ukraine, and Britain and the US expressed their fear that Russia could use a chemical weapon in Ukraine.
Although these terms are not new, they might be alien to many. Here’s what they mean.
Dirty Bomb
Dirty bomb, also called radiological dispersion device (RDD), is an explosive device designed to scatter radioactive material, hence the adjective dirty. Unlike an atomic bomb’s explosive power, which comes from a nuclear chain reaction, the explosive energy of the dirty bomb comes from ordinary conventional explosives such as dynamite or TNT. When the dirty bomb detonates, it scatters radioactive material that has been placed in close proximity to the explosives. (https://www.britannica.com/technology/dirty-bomb)
Security analysts believe that the comparative ease with which the components of a dirty bomb can be obtained make it an attractive option for terrorists or for countries that do not have the resources to build a nuclear weapon. There have been no recorded instances of a successful dirty bomb attack. Scattering radioactive material as a weapon was first suggested in 1941 by a committee of the US National Academy of Sciences led by physicist Arthur Holly Compton, and from 1949 to 1952 the US Army also tested explosives designed to disperse radioactive tantalum.

Thermobaric or “Vacuum Bomb”
“The thermobaric weapon, also known as an aerosol bomb or fuel air explosive, is a two-stage munition. The first-stage charge distributes an aerosol made up of very fine material – from a carbon-based fuel to tiny metal particles. A second charge ignites that cloud, creating a fireball, a huge shock wave, and a vacuum as it sucks up all surrounding oxygen. The blast wave can last for significantly longer than a conventional explosive and is capable of vaporising human bodies. The bombs have been used by Russian and western forces since the 1960s. The US relied on them in its attempts to eliminate Al-Qaida in the mountains in Afghanistan.” (The Guardian, 1 March 2022, “What are thermobaric weapons and how do they work?”)
Dr Marcus Hellyer, senior analyst at the Australian Strategic Policy Institute said that thermobaric weapons were effective at their ‘specific purpose’ of ‘primarily destroying defensive positions’. Whilst they would not be used to penetrate a tank, they could be a ‘very destructive weapon’ against an apartment complex or other building.
They are not illegal even though their effects can be pretty horrific, because of that effect of creating a vacuum and sucking the air out of the lungs of defenders”, he said. (Ibid)
Biological Weapons
The World Health Organisation says biological weapons are microorganisms like virus, bacteria, fungi, or other toxins that are made and released deliberately to cause disease and death in humans, animals or plants.
“Biological agents, like anthrax, botulinum toxin and plague can pose a difficult public health challenge causing large numbers of deaths in a short amount of time while being difficult to contain. Bioterrorism attacks could also result in an epidemic, for example if Ebola or Lassa viruses were used as the biological agents. Biological weapons is a subset of a larger class of weapons referred to as weapons of mass destruction.” (https://www.who.int/health-topics/biological-weapons#tab=tab_1)
Chemical Weapons
Modern use of chemical weapons started with World War I, when both sides used poisonous gas to inflict agonising suffering and cause significant battlefield casualties.
They consisted of well-known commercial chemicals put into standard munitions such as grenades and artillery shells. Chlorine, phosgene (a choking agent) and mustard gas (which inflicts painful burns on the skin) were among the chemicals used.
The UN explains on its website: “The results were indiscriminate and often devastating. Nearly 100,000 deaths resulted. Since World War I, chemical weapons have caused more than one million casualties globally. As a result of public outrage, the Geneva Protocol, which prohibited the use of chemical weapons in warfare, was signed in 1925. While a welcome step, the Protocol had a number of significant shortcomings.”“Poison gasses were used during World War II in Nazi concentration camps and in Asia, although chemical weapons were not used on European battlefields. The Cold War period saw significant development, manufacture and stockpiling of chemical weapons. By the 1970s and 80s, an estimated 25 States were developing chemical weapons capabilities. But since the end of World War II, chemical weapons have reportedly been used in only a few cases.” (https://www.un.org/disarmament/wmd/chemical/)
