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 Modern Nuclear Family THE MODERN NUCLEAR FAMILY The "nuclear"‚ "isolated"‚ or "restricted" family is not a recent phenomenon‚ but has existed in many cultures throughout human history. Indeed‚ the extended family of several generations is found mostly in relatively advanced‚ stable‚ and affluent‚ but not yet industrialized societies. Very primitive and very sophisticated societies seem to prefer the nuclear family model. However‚ nuclear families can vary in the

Nuclear Meltdown Throughout human history‚ there have been and continues to be scandals and cover-ups made by the government and city officials to save their own behinds. Where have all the honest people gone? No matter what the case maybe‚ money and a good reputation seem to prevail over the cost innocent lives. In 1959‚ Rocketdyne‚ a rocket-testing company in the Santa Susana Hills of Simi Valley had a meltdown. Although Rocketdyne representatives deny that the incident caused any type

Computer Misuse Act 1990 Another legal issue linked with information issues within an organisation is the Computer Misuse Act 1990. This states that it is against the law to commit a crime using a computer and that anything that is against the law in the ‘real’ world is equally illegal in the ‘virtual’ one. This basically means that it is illegal to physically break a computer but if you use a virus it is equally illegal as it is still breaking the computer but using a ‘virtual’ method. Before 1990

Radioactive Decay‚ Nuclear Fission and Nuclear Fusion When elements undergo radioactive decay the atoms of one element are changed into the atoms of another element when an alpha or beta particle is emitted from an unstable nucleus. When a nucleus disintegrates and emits an alpha particle it is alpha decay‚ the alpha particle emitted contains two protons and two neutrons which is equivalent to a helium nucleus being released. Alpha decay occurs because there are too many protons‚ which causes

determined. Only from the 1920s there were methods of calculating what elements were present in a gas by just observing its spectrum‚ due to the fact that different elements absorb and emit different wavelengths of light. (2) Gamow thought that nuclear fusions took place in the first minutes after the Big Bang‚ because he assumed that the initial components of the universe would have been seperate protons‚ neutrons and electrons. He hoped that they could build bigger atoms by fusion in the heat

In nuclear chemistry‚ nuclear fusion and nuclear fission are different types of reactions that release energy due to the presence of high-powered atomic bonds between particles found within a nucleus. In fission‚ an atom is split into two or smaller‚ lighter atoms. Fusion‚ in contrast‚ occurs when two or smaller atoms fuse together‚ creating a larger and heavier atom. In both reactions‚ large amounts of energy are produced‚ with the only difference that fusion generates three or four times more energy
