AND WHILE WE’RE CONTEMPLATING NUKES…
…let’s ponder a bit of dangerous science.
“This is because the uranium is not enriched. A nuclear bomb fueled by uranium releases energy through fission, the breaking apart of an atom. When a neutron hits the nucleus of a uranium atom, the atom breaks apart. The resulting pieces weigh slightly less than the original whole; that weight having been turned into huge amounts of energy. Here's the key – each split nucleus has to release at least two neutrons of its own. They hit other nuclei and start two more reactions, and those atoms release more neutrons and start more reactions. The result is either a steady hum of energy or a big boom, depending on how you work it. Let's face it. If it were that simple, nuclear bombs would have been invented long ago. If there's one thing the internet proves, it's that people will never stop looking for flashy ways to hurt themselves and others. The reason why everything, from the pyramids to the Eiffel Tower aren't reduced to little particles of dust wafting around the upper atmosphere is only very, very rare isotopes of uranium break apart easily enough and give off enough neutrons to sustain a nuclear reaction. The most common uranium isotope is uranium-238, with ninety-two protons and 146 neutrons. It doesn't sustain a reaction. Uranium-235, with 143 neutrons, is the money isotope.” (Click here for more)
