occurring radioactive elements found in the Earth. We are also exposed to man-made radiation including medical radiation. Nearly half of the radiation in which the US population is exposed to comes from medical sources such as CT scans‚ x-rays‚ and nuclear medicine. In 1899‚ Ernest Rutherford discovered that the radiation emitted by uranium consisted of two kinds of rays: one with weak penetrating power‚ (alpha rays) and another with stronger penetrating power (beta rays). A third and even more penetrating

A disaster is a natural or man-made (or technological) hazard resulting in an event of substantial extent causing significant physical damage or destruction‚ loss of life‚ or drastic change to the environment. A disaster can be ostensively defined as any tragic event stemming from events such as earthquakes‚ floods‚ catastrophic accidents‚ fires‚ orexplosions. It is a phenomenon that can cause damage to life and property and destroy the economic‚ social and cultural life of people. In contemporary

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

Nuclear power generation involves the use of large nuclear fission reactors that generate electricity through fission reactions and heat generation. Nuclear energy has many positive externalities but in the past the technology has proven that it has major downfalls as well

The social construction of disasters evolves throughout the years due to political and economic factors as well as education and technological advancement. One thing is that disasters are commonly understood to be limited in both time and effect (Hills‚ p.163). When analyzing and interpreting past‚ present and future political synergies‚ it is necessary to include a human dimension that encapsulates and embraces socio-cultural appreciation and understanding of man and his environment (Trim‚ p. 218)

Nuclear Power Assignment -Containment structure: This is usually a big concrete dome or structure that protects workers and the area around it from potentially dangerous radiation. The walls of the structure are metres thick of concrete to absorb the radiation. -Reactor: The reactor is the most important part of the process as it produces heat which forms steam to power the turbines therefore creating electricity. It uses uranium-235 or in some cases plutonium-239. -Control rods: Control

keeping Nuclear Weapons Should the United States keep and maintain nuclear weapons today? Yes‚ because without nuclear weapons we would not be able to have the protection we have today since the threat of nuclear war. Which the odds of that happing are very slim since these weapons of mass destruction cause so much damage‚ but if the U.S where to get rid of the nuclear weapons today that would leave a huge vulnerability slot for us since the other countries would very well keep their nuclear weapons

Smuggling of Nuclear Material Over the past five years the former states of the Soviet Union haven ’t been able to prevent the leakage of nuclear material. Nuclear materials and technologies are more accessible now than at any other time in history‚ due to the breakup of the Soviet Union and the worsening of economic conditions. No longer does the Soviet KGB‚ the Soviet military and the Soviet border guards have the control to stop the smuggling of nuclear material ’s. With the Cold War

occurrences were becoming disaster‚ together with being documented in various ways providing a warning for the future generation. However in 1920‚ there was a published study referred to as the catastrophe and social change by Henry Samuel Prince. This was the Halifax Disaster documented account and the occurrence of the social change. The first person to deliver evidence based study was Prince‚ by use of theory founding a paradigm which paved way for the management of disaster to be studied (Sperling
