Atomic energy can be used for power generation. In England it has been used for several years to heat houses in a small area. The United States of America has successfully employed atomic fuel in a submarine which can go to all the seas and remain under water without the need for refueling. Russia has put into operation an atomic electric station of 5,000 Kwts. Within the next ten years or so many atomic power stations will be set up all over the world. Atomic energy has entered the farms, the factories, the power houses, and the hospitals.
A significant application of atomic energy in the field of agriculture has been in the use of radioactive tracers in fertilizers. Radiation, when directed on seeds and plants, increases the crop output. Experiments are going on to find a method of killing harmful bacteria by radiation. This will keep food fit for human use for longer than is possible new. It will be possible to produce food by laboratory process.
In the field of medicine it has already made great advances. In course of time it is going to revolutionize the field of Medicine and give us the means to fight those diseases which are now considered beyond cure. Radioisotopes are used for medical operations. Radioactive cobalt can be employed to cure cancer.
In the field of industry its uses can be enormous. In the U. S. A. many firms are applying atomic energy to obtain better products at a lower cost. Some countries have already started building electric plants which use atomic energy.
Another important field in which atomic energy will bring about revolutionary changes is communication. In a few years we can expect atomic energy to be used for ocean going vessels, trains and air-crafts. Isolated and barren lands will again become centers of activity. This new source of power can supply heat and light to villages hidden in far away valleys.
Industrialization has so far proceeded on the basis that most of the materials needed will be available. 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. In developed countries they are not sufficient for the attainment of a standard of living equal to that of industrially-advanced countries. Atomic energy 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 man a huge power of destruction. If wise use is not made of this 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. Although their full effects are not known, enough is known to show that such nuclear weapons endanger the very existence of the human race. If another World War breaks out, millions would be killed and injured. And millions more 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.
Apart from the heat and blast effects of such weapons, men 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 slow death. Not only the present but the future generations are also subject to the dreadful effects.
