One atomic bomb is a powerful weapon made by breaking atoms of the element uranium.

Radiation is emitted when the nucleus of a heavy element like plutonium or uranium divides or splits. Even years after an atomic attack, the devastation caused by radioactive radiation can continue to sicken and kill individuals.

Atomic bombs are sometimes called a-bombs, nuclear bombs, nuclear weapons, and nukes.

Nine nations presently possess atomic warheads which can be utilized in warfare.

According to estimates, there are around 15,800 nuclear weapons in the hands of the nine countries that hold them as of 2014.

The United States orchestrated two nuclear bombings in the Japanese cities of Hiroshima and Nagasaki in 1945, thus ending World War II.

The atomic bombing of Hiroshima in Japan during World War II occurred on 6th August 1945. It went off at a height of 2,000 ft (600 m) above the Japanese city, causing a burst of flames and intense light.

Around 140,000 people perished in the first five days.

On 9 August, the Japanese city of Nagasaki was destroyed when another bomb was dropped, killing an estimated 75,000 people.

The Invention Of Atomic Bomb

This deadly weapon came into existence many years ago. Let's find out more about its origins.

  • The atomic bomb is a missile of mass devastation that uses a nuclear reaction to create a large explosion.
  • Nuclear weapons are divided into two categories: fission and fusion.
  • The explosion of nuclear weapons, often known as an atomic bomb, is caused by a nuclear fission reaction.
  • The explosion of a fusion bombing, also known as a thermonuclear device or hydrogen bomb, is caused by both fission and fusion reactions.
  • The United States, which had identified atmospheric radioactive traces created from its test facility inside the Kazakh Soviet Socialist Republic, broke the news of the first Soviet bomb to the rest of the world first.
  • The Manhattan Project was a top-secret effort by American scientists and engineers.
  • The Manhattan Project was named as such after Columbia University in Manhattan, New York, which was one of the first atomic bomb research centers in the United States.
  • It resulted in the introduction of atomic weapons and flagged a key turning point in the initial Atomic Age.
  • For the endeavor, the U.S. military partnered with the brightest brains of the research world.
  • In just four years, the United States spent almost $2 billion on the Manhattan Project.
  • Several scientists emigrated to the United States in the late 30s, carrying the knowledge of the fission discoveries with them.
  • Albert Einstein was called by Leo Szilard, who, despite his reservations, was persuaded by fears that Nazi Germany might go through with atomic bombing first.
  • Expensive trials began, among other places, at the University of Chicago.
  • Reactors were developed in Washington, Oak Ridge, and other locations to begin and regulate nuclear chain reactions.
  • Scientists worked tirelessly, yet the first bomb did not come into being until 1945.
  • A test explosive code-named 'The Gadget' was delivered to a facility in New Mexico that summer.
  • On 16 July 1945, at 5:30 a.m., the bomb was dropped, signaling the start of the Atomic Age.
  • A powerful flash, a surge of heat, a huge shock burst, and a cloud of smoke spanning 40,000 ft (12,192 m) into the skies were all witnessed.
  • Thousands of yards of adjacent desert sand were converted into spectacular jade greenish radioactive glass when the tower imploded.

The Destruction Caused By Atomic Bombs

As we know by what happened in Hiroshima and Nagasaki, atomic bombs cause devastation to the areas they hit. Let's look at their effects in more depth:

  • Atomic bombs are very deadly; a single high-yield bomb blast may destroy an entire city, killing millions and causing widespread fallout.
  • A conceivable result of nuclear warfare is a nuclear winter.
  • A comprehensive nuclear war is thought to have a significant and long-term cooling effect on the global climate.
  • Essentially, the ash from all of the destruction of the nuclear weapons would obscure out the sun, causing the Earth to become significantly cooler.
  • Atomic bombs are nuclear bombings that cause large explosions by utilizing the energy output of nuclear fission.
  • Hydrogen bombs, on the other hand, employ combined fission as well as a fusion to generate their increased explosive potential.
  • Only two nuclear bombings have ever been used in combat, each by the United States after World War II.
  • Approximately 2 million Japanese people were killed by the two atomic bombs, and the majority of them were civilians.
  • More life was lost to radiation illness as a result of the fallout, which allowed radioactive elements to shower down on Japanese survivors of the bomb blast.
  • Survivors of the atomic bombing inadvertently passed radioactivity on to their offspring.
  • Even though governments throughout the globe have continued to build nuclear weaponry, there are already initiatives to support nuclear disarmament, and key world powers have signed anti-nuclear treaties.
  • Even towns and nations that were not directly targeted would be contaminated by fallout.
  • Extremely dangerous fission products would disseminate throughout the globe via typical weather patterns and lodge in soil and water.
The US is the only nation that has ever used nuclear weapons in a conflict.

How The Atomic Bomb Worked

We now know how the atomic bomb was invented and the effects that it has but let's look at little closer at the science behind how it works:

  • When a single neutron collides with a fissile atom's nucleus, it divides into separate smaller atoms known as fission fragments, as well as extra neutrons.
  • As it creates additional neutrons at the rate necessary to induce fresh fissions, fission can be self-sustaining. Chain nuclear reactions were started as a result of this.
  • Two techniques have been used to simulate the detonation of an atomic weapon.
  • The gun-type assembly compresses from one side with a conventional explosive, but the implosion assembly pressures from all sides at the same time.
  • The kinetic energy of the loaded fission pieces flying through the air from each other accounts for 93% of the energy.
  • The charged fragments' large electric charge, on the other hand, generates multiple inelastic collisions with surrounding nuclei, trapping them inside the uranium bomb.
  • The material in the bomb's core and tamper gets transformed to plasma at a level of thousands and millions of degrees and has a diameter of several meters.
  • The boom and flames produced by this X-ray radiation are often the results of a nuclear detonation.
  • The Hiroshima and Nagasaki bombings, carried out by the United States upon Japan at the end of World War II, remain the sole use of atomic warheads in hostilities to this day.

Facts About Atomic Bomb

J. Robert Oppenheimer was the Manhattan Project's senior scientist. He is frequently referred to as the 'father of the atomic bomb'. Here are some more facts about the atomic bomb:

  • Uranium was used in the first bomb detonated on Hiroshima. The plutonium bomb that was unleashed on Nagasaki was even more destructive than uranium.
  • At least 135,000 people were killed in the Hiroshima bombing, with another 70,000 killed in Nagasaki. Many of these individuals, including women and children, were civilians.
  • Hiroshima was chosen as the site of the bombing because it was a big port city with a military installation.
  • It had also been relatively unscathed by previous bombings, demonstrating the new weapon's potency.
  • The Manhattan Project made the United States of America the first country to create a nuclear weapon.
  • Trinity was the secret title for the very first man-made nuclear explosion, which occurred at 5:29 a.m. PST on 16 July 1945.
  • The Trinity test yielded 22 kilotons of TNT, according to calculations.
  • An intercontinental ballistic missile (ICBM) is a missile capable of carrying a nuclear payload over a distance of at least 3,400 mi (5471.8 km).
  • Military targets are hit with a tactical nuclear weapon.
  • Cities are targeted with a strategic nuclear weapon.
  • A submarine-launched ballistic missile (SLBM) is a nuclear-capable ballistic missile that can be fired underwater from a submarine.
  • The United States of America, Russia, the United Kingdom, France, China, India, Pakistan, North Korea, and Israel are the nine countries that have nuclear weapons.
  • Although Israel has never claimed to possess nuclear weapons, analysts think it has possessed them since 1966.
  • The United States of America and Russia control over 90% of all nuclear weapons in the world.
  • Shortly after the Soviet Union began work on its atomic weapon program, and not long after that, both countries were working on even more destructive fusion weaponry termed 'hydrogen bombs'.
  • The Tsar Bomba, a hydrogen bomb produced by the Soviet Union, was the biggest nuclear explosive ever exploded.
  • A hydrogen bomb named Castle Bravo was the heaviest nuclear weapon ever exploded by the United States.
  • During World War II, the United States of America launched two nuclear attacks on Japan.
  • The United States of America dropped the first nuclear bomb above the city of Hiroshima, Japan, on 6 August 1945.
  • The United States of America went through with the Nagasaki bombings in Japan, on 9 August 1945.
  • In the 50s, the United Kingdom and France developed their own nuclear weapons systems, and the number of governments having nuclear weapons has steadily increased in the decades afterward.
