Nuclear power‚ or nuclear energy‚ is the use of exothermic nuclear processes carried out in controlled manner‚ to generate useful heat and electricity. Nuclear power works by using the energy from nuclear fission or fusion to generate heat. At the moment‚ nuclear fusion is still a subject of intense research and not used in production which is a pity. Nuclear fission is basically what is happening in a reactor. Radioactive elements have unstable nuclei and they are constantly going through random

Fusion as a future energy source Creating Nuclear Fusion could be a break through in finding an alternative source of energy. As of today we do not have the technology to make a nuclear fusion reactor‚ but we could be relying on them for power sometime in the next 30 to 40 years. Nuclear Fusion is created by forcing deuterium (D) and tritium (T) together‚ when forced together their nuclei fuse and then break apart to form a helium nucleus and an uncharged neutron. Most of the excess energy

It has very a lot of arable land and large reserves of natural resources. The warm climate favours the production of most crops and livestock which is in demand by the population. The country’s economic backbone lies between the performance of the mining and agricultural

Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine

The instant a one megaton nuclear bomb is dropped everyone within a six mile radius of the drop site will be instantly vaporized. The people will literally not have known what hit them‚ because they will have vanished before the electrical signals from their sense organs can reach their brains. These are the people who are lucky‚ when it comes to a nuclear bombing. Those within a ten mile radius will have instantly become blind‚ and people even further away would become blind if they were looking

Nuclear Radiation There are many ways that the movie The Day the Earth Stood Still and the short story "There Will Come Soft Rains" are similar. "There Will Come Soft Rains" by Ray Bradbury is a science fiction story that deals with nuclear radiation and what the future world would be like if there was an atomic bomb. This short story is a good example of what could happen in the future. The Day the Earth Stood Still is a movie that also has the same genre‚ that it is science fiction. It helps

that India will test a nuclear weapon in the coming years are not high. But if India again surprises the world as it did in 1998 with five nuclear explosions in the desert of Rajasthan‚ then conversations on the implications for the Indo-U.S. civil-nuclear deal will begin. The record of debate on testing during negotiations reflects the depth of American concern that testing will lead to unstable nuclear escalation and the lengths the U.S. went to in order to deter India from conducting new tests.

Rosemary Hurrey EAS-101-OL009 10 July 2013 Written Assignment 1 Answer the following questions. 1.Summarize advances over time in determining the age of the Earth‚ including the importance of the discovery or radioactivity. Throughout the past few decades‚ there have been advancements in new techniques to help determine the age of the Earth. Currently scientific evidence believes that the Earth is between 4.5 and 4.6 billions years old. To help determine the age of the earth‚ radiometric dating

Assess the reasons why British attitudes to Europe changed from 1945-1973. [50] After the war‚ Britain retained a great sense of national pride as they had not been defeated by the war in the way other European countries had such as France‚ Germany and the Benelux countries. They had their economic and political regimes upheaved and needed co-operation to ensure they could rebuild. Britain was keen for peace throughout Europe‚ especially with the Soviet’s influence spreading; however they were not

In spring of 1989‚ two scientists by the name of Stanley Pons and Martin Fleischmann announced that they had found a way to create nuclear fusion in a relatively simple and cheap way. Superhot fusion is the process in which deuterium‚ a heavier form of hydrogen‚ is held within a magnetic field and heated to tens of millions of degrees. The nuclei of the atoms fuse‚ and heat energy is released. This kind of fusion happens in our solar system’s sun. This type of fusion is known to occur‚ but recreating
