Essay On Nuclear Development And Its Impact
Due to the intensive scientific research during the Second World War, nuclear energy and the nuclear weapons were invented. In 1945, the world witnessed the devastating effects of nuclear energy when two bombs were dropped on Japanese cities Hiroshima and Nagasaki. Half of the population of the country had perished.
It seems the world has not learnt any lesson from what had happened to Japan. Today, five nuclear powers of the world are United States of America, China, Russia, England and France. With the passage of time, they have increased the stock of nuclear weapons. They do so in the name of national security. The supporters of nuclear power say that it is clean, safe and cheap to develop nuclear weapons. On the other hand, the critics say that it is environmentally destructive, dangerous and expensive. The nuclear energy began to be developed for civil uses only during the late 1950s. However, its development and progress never kept its promise.
In 1957, International Atomic Energy Agency was formed by United Nations Organization to exchange and encourage the contribution of atomic energy for peace and prosperity throughout the world. The Government of USA gave grant to many countries to build nuclear research reactors. By the end of 2000, there were nearly 400 atomic reactors and many are under construction. However, the speed of nuclear development around the world has slowed down due to high cost involved in it and environmental degradation caused due to it.
The nuclear tests are conducted in the atmosphere, under water, under the ground or even in the space. The impacts of such tastings are both local and global due to health injuries and deaths. Due to widespread protest from people, most of the underground nuclear tests are cancelled. Although underground tests are conducted at a safe place, some radioactive materials escape in the atmosphere.
Nuclear explosions causes earthquake like tremors. This creates long-term damage to the rock formation in the surrounded areas. Radioactive elements that are released during nuclear testing contaminate the atmosphere. The ground water coming at the surface of the earth is also polluted.
In short, one can say that there are numerous harmful effects on human health and environment in the entire chain of nuclear testing and producing nuclear weapons.
