It is known that the reserves of a number of metals will not last for more than a few decades. The industrialization of new areas of the world will be checked if no other way is found. Atomic -energy has now given us new hope. The source of the energy used in the world today is coal oil and gas, and hydro-electric power. The present known reserves of coal and oil are limited. Atomic energy here has a great role to play. It has been estimated that uranium and thorium contain enough atomic energy to meet the needs of the under-developed countries.
Atomic energy will also enable the advanced countries to maintain a high standard of living for centuries to come. The extent to which atomic energy is put to general use will depend upon capital and running costs involved and the very high quality of technical skill needed.
At present atomic energy is extremely expensive. Its technology is very difficult. Development of new methods and techniques, along with greater education in atomic science will solve this problem.
While atomic energy has come as a great liberator of humanity, it has given to men vast power of destruction, it wise use is not made of the energy its ultimate dreadful consequences may outweigh the good it can do. We are living today under the shadow of nuclear weapons.
The known consequences of the explosions of these are too horrible to think of though their full effects are not known, enough is known to show that such weapons endanger the very existence of the human race If another World War breaks out millions will be killed.
Many millions injured and many more millions will die a slow and painful death. All over the world there have been protests against the tests of such weapons. There is also a move to get these weapons banned. Nobody knows for certain if the leaders of the two Great Powers will realize this danger to mankind and take a pledge not to use atomic power for destructive purposes. A part from the heat and blast effects of such weapons, man like Einstein and Bertrand Russell have warned against the radiological effects of nuclear explosions.
A number of radio-active substances, such as radio-strontium, enter into the body, soil, air, water and food. This brings about various diseases, life shortening and giving show death.
Not only the present but the future generations are also subject to the dreadful effects. The future of atomic energy is full of hope and danger. Share to Twitter Share to Facebook. Newer Post Older Post Home. But on a fateful day in when the U. How exactly is energy got from the atom? For the atom, as we know, is the tiniest speck of matter? Each atom has a central core called the nucleus, around which revolve the electrons. The nucleus is built up of two kinds of very minute particles called protons and neutrons.
The electron has a negative electrical charge, the proton has an equal positive charge and the neutron has no charge. The nucleus of the radium atom constantly disintegrates ejecting alpha particles which are the nuclei of helium atoms. This phenomenon is called radioactivity. Uranium is another radioactive element. In Hahn and Strassman bombarded uranium with neutrons and found traces of barium in the material.
This led to the discovery that some of the uranium atoms capture a bombarding neutron and get split into two nearly equal parts. This splitting is called nuclear fission. At the same time two or three neutrons are set free in the reaction. These go on splitting other uranium atoms and release neutrons. This is called a chain reaction and, in its wake, enormous amounts of heat and gamma rays which are X-rays of very short wavelength and great penetrating power are released.
This knowledge was utilised in the preparation of the atom bomb. Such a weapon had become imperative in view of the mounting supremacy of the Germans and Japanese in the World War.
After three years of intensive work atom bombs were perfected.
Aug 26, · Atomic energy has entered the farms, the factories, the power house, and the hospitals. A significant application of atomic energy in the field of agriculture has been in the use of radioactive tracers in fertilizers.
Essay on Nuclear Energy Words | 7 Pages. Nuclear Energy Nuclear energy-This is energy that binds together components of an atomic nucleus. This is made by the process of nuclear fission. Nuclear fission is produced when an atomic atom is split.
Hire the term atomic energy levels, , scholarship news on august 6 were the atom. Since they spawned thoughts of papers, or alternative to produce large atomic energy good and safeguards. Lenr the economic and gilbert atomic energy: //www. Commentary and over atomic energy resource, the regulatory compliance and the 5 deals with confidence. Essay: Nuclear Energy – Advantages and Disadvantages Abstract “Growing concerns over climate change have highlighted the need to step up contribution of nuclear energy in the energy mix and to reduce the dependence on fossil fuels in the years to come.
Atomic Energy and Nuclear Weapons Essay - Atomic energy is “the energy that is released through a nuclear reaction or radioactive decay process”(fashionlosdaeroh.cf). Jordan Termine stated, “According to Einstein’s researches, in , he concluded the possibility of setting up a nuclear chain reaction in a large mass of uranium, by which vast. Atomic energy By: Hiram A. Murray III Background info The origin of the phrase atomic energy check in from the years of It is defined as energy released by reactions within atomic nuclei, as in nuclear fission or fusion.
