=HOW AN ATOMIC BOMB WORK?= //**An __atomic bomb__ works by initiating a nuclear chain reaction, which releases a huge amount of energy relative to conventional explosives. Per unit volume, an atom bomb may be millions or billions of times more powerful than TNT. When an atomic bomb occurs it creates a nuclear reactions which is when neutrons are fired at closely packed atoms with heavy nuclei (uranium or plutonium isotopes). These heavy nuclei break apart into lighter nuclei when hit by a neutron, in turn generating more neutrons which bombard other nuclei, creating a chain reaction. This process is known as fission. (Another process known as fusion releases energy by fusing together nuclei rather than breaking them apart.) By breaking down the nuclei themselves rather than releasing energy through a conventional chemical reaction, atom bombs can release more than 80 terajoules of energy per kilogram (TJ/kg).**//

 * //__Karen Silkwood__ was born on February 19, 1946 and she was a chemical technician at the Kerr-McGee's plutonium fuels production plant in Crescent, Oklahoma, and a member of the Oil, Chemical, and Atomic Workers' Union;//** **//she was also an activist who was critical of plant safety. While she was working in the laboratory she was expose with plutonium and became saturated with crap. Karen Silkwood died in a fatal one-car crash on November 13, 1974.//**

=THE NUCLEAR EXPLOSION IN CHERNOBYL=
 * //The __Chernobyl nuclear__ power plant in the Ukraine exploded on April 26, 1986 which caused several disasters in Chernobyl. The reason for the disaster of Chernobyl is that the plant was not properly designed and could only be run with very specific instructions. Also//** **//the operators of the plant failed to properly follow these instructions, and some scientists conducted a highly risky experiment that led to the explosion. With the lack of following instructions, the Chernobyl power plant caused things to blow up like the pressure on the reactor's roof blew everything inside; which included molten uranium, burning graphite, and radioactive ashes that were emitted into the atmosphere. When the explosion in Chernobyl occured, it was possible that the radioactive of the explosion might give 2300 people cancer.//**
