Nuclear Weapons Weird Facts

Anything from Hirosima to James Bond may come to mind when yo think of nuclear weapons. At any rate, extreme danger always enters the picture. There is nothing soothing about these deadly pieces of machinery but this is information will hopefully pull back a little of a cloak from their mystique…
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 modern thermonuclear weapon weighing little more than a thousand kilograms (2,200 pounds) can produce an explosion comparable to the detonation of more than a billion kilograms (2.2 billion pounds) of conventional high explosive. Thus, even single small nuclear devices no larger than traditional bombs can devastate an entire city by blast, fire and radiation. Nuclear weapons are considered weapons of mass destruction, and their use and control has been a major focus of international relations policy since their debut.


In the history of warfare, only two nuclear weapons have been detonated offensively, both near the end of World War II. The first was detonated on the morning of 6 August 1945, when the United States dropped a uranium gun-type device code-named “Little Boy” on the Japanese city of Hiroshima. The second was detonated three days later when the United States dropped a plutonium implosion-type device code-named “Fat Man” on the city of Nagasaki, Japan. These two bombings resulted in the deaths of approximately 200,000 Japanese people (mostly civilians) from acute injuries sustained from the explosion. The role of the bombings in Japan’s surrender and the U.S.’s ethical justification for them remains the subject of scholarly and popular debate.
