A nuclear explosion is caused by the release of energy in an atom‚ either through fission or fusion. Fission weapons cause an explosion by the splitting of atomic nuclei. This happens when a neutron collides with the nucleus of an atom. The protons in the nucleus are transformed into a great amount of energy and two or three more neutrons are sent out‚ which go on to split other nuclei. If this continues‚ a chain reaction will occur. The result is a gigantic explosion. To form a chain reaction‚ a

To give you a basic idea on how the process of converting energy works according to the Canadian Nuclear Association is as basic as‚ “splitting the uranium atom to generate the heat that is used to produce steam for the production of electricity”(www.cna.ca). However things do not always run so smoothly‚ and the leakage of the nuclear material could have devastating

The Chernobyl Nuclear Power Plant Disaster It is a silent enemy‚ it has no odor‚ no smell‚ no shape‚ yet it is one of man’s deadliest foes. Radiation is not something most people face on a daily basis‚ but for the town of Prypiat in the Ukraine it is a barren wasteland because of it. The Chernobyl Nuclear Power Plant disaster was the worst nuclear catastrophe to have ever occurred and‚ is a perfect example of what can happen when the blind and unmasked furry of atomic power is left unharnessed

In 1950‚ the first commercial nuclear power plants were constructed. The public was promised a non-polluting and resourceful type of energy‚ but how safe was‚ and is‚ nuclear energy? Although there are less than 500 licensed nuclear power plants in the world‚ many nuclear accidents have already been endangering civilian lives. More serious accidents are not just likely‚ but inevitable (Fairchild 29). Nuclear energy may appear to be the ideal source of energy for the future: however‚ there

Cause and Effect The Effects of Global Warming Global warming is one of the greatest threats to humanity and to the environment. Global average temperature rose significantly during the past century. The current scientific view is that most of the temperature increases since mid-20th century has been caused by increases in atmospheric greenhouse gas concentrations produced by human activity. Most scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue

THE NEGATIVE PHYSICAL EFFECTS OF NUCLEAR RADIATION Page 1 Abstract Nuclear radiation has been a major problem since 1941 when the Second World War began. A major contribution to World War Two is the nuclear bomb‚ also known as the Atom bomb. Once the two bombs were dropped‚ the usually terminal Leukemia was derived throughout Japan. There are three types of radiation‚ Alpha‚ Beta‚ and Gamma radiation. In my study of radiation I discovered that radiation can damage many cells in your body

Nuclear war is something that we have all heard about. It seems to be overdramatized in movies. But perhaps the movies are right. Maybe we are on the brink of a chasm so dark and ominous that it drowns out all faith and light. A nuclear holocaust occurring would wipe out all of civilization as we know it. We would be essentially thrown into a dark age. Never in the history of the world has there been such a dramatic event‚ but that does not mean that it cannot happen. "Once we all lived in peace
