to further global warming‚ forcing society to seek other forms of clean‚ high-density energy. While renewable resources such as hydroelectric‚ solar‚ and wind energy are worthy substitutes‚ they are not yet ready to meet the world’s energy needs. Nuclear power is an attractive energy source‚ as it doesn’t emit greenhouse gases and can be used on a large scale‚ producing over 20% of electricity in the United States.1 Although with any energy solution‚ comes consequences.

Nuclear Energy – Blessing or Curse? Nowadays hot debates surround use of nuclear energy. It is widely suggested that it is one of the cheapest and cleanest energy resources‚ whereas others strongly disagree with that viewpoint‚ and claim that use of nuclear energy poses an unacceptable risk to the environment and to humanity. Consequently‚ there are many demonstrations against nuclear power plants worldwide‚ whereas others consistently support nuclear energy. Where does the truth lie? One of the

Advantages of a nuclear family are: 1.) Stability. A child raised by the same two parents during their maturing years is more likely to have emotional bonding and relationship stability. Children raised by a single parent will likely have a sense of loss for the missing parent and lack the advantage of duel insights‚ emotional support and examples that come from having both a mother and a father. 2.) Legacy. A nuclear family of a husband and wife provides a life long consistancy of purpose

Together nuclear power plants and hydroelectric dams provide about 50% of the power generated for the United States doing so in a clean and efficient manner. Both systems have their ups and down‚ radiation and disrupting ecosystems for example‚ but their benefits far outweigh the small risks and problems they create. We have progressed in leaps and bounds in power development making these two much safer and efficient than most other ways to generate electricity. Hydroelectric dams create a substantial

About Radiation: Radiation is an energy that is transmitted in the form of waves or tiny particles. These are electromagnetic waves‚ which are classified as ’ionizing radiation’ and ’non ionizing radiation’. Electromagnetic radiation is when an object gives out electromagnetic radiation. For example when you on a torch light‚ the light is an example of radiation. Ionising radiation has more energy than non ionising radiation. Therefore it is enough to cause chemical changes by breaking chemical

approved of the funding for the nuclear weapon because of several events prior to his public announcement. One of the reasons was the fact that the United States had lost its nuclear supremacy when the Soviet Union successfully detonated an atomic bomb at their test site in Kazakhstan in 1949. Another reason why he decided to fund experiments for nuclear weapons is because the British and U.S. intelligence discovered that Klaus Fuchs‚ a top-ranking scientist in the U.S. nuclear program‚ was a spy for the

treatment with radiation I am for the use of radiation because it can be used in many good ways. My sub group is medicine. I am researching a radiation treatment used for helping cancer patients. This is a good use of radiation because it kills the cancer cells and may even cure the cancer. It doesn’t always cure it but it will slow the process down. One reason radiation therapy is used‚ is to destroy the cancer cells. It is also for shrinking tumors. Tumors are mostly cured by the radiation. It can also

Social scientists have noticed that the concept of the family has changed in the past 40 years‚ and this has led some to comment on the ’disintegration of the nuclear family’. Do you agree with the claim that the nuclear family unit is breaking down? The conventional nuclear family model‚ Murdock first spoke of‚ which entails the father as the employed bread winner and the wife as the stay at home housewife and mother looking after their children. This early idealistic model of the stable family
