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

What is nuclear medicine? Nuclear medicine is a division of medical imaging that detects and treats diseases and irregularities in the body such as cancer and neurological illnesses through the use of radioactive chemicals. The techniques used in nuclear medicine allow physicians to attain knowledge about patient conditions without the invasion of personal space through procedures such as biopsies. The equipment and machines used within this branch are important for research as they allow for a better

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

Nuclear engineering is the practical application of the breakdown of atomic nuclei and/or other sub-atomic physics‚ based on the principles of nuclear physics. It includes‚ but is not limited to‚ the interaction and maintenance of nuclear fission systems and components specifically‚ nuclear reactors‚ nuclear power plants‚ and/or nuclear weapons. The field may also include the study of nuclear fusion‚ medical and other applications of (generally ionizing) radiation‚ nuclear safety‚ heat/thermodynamics

The Nuclear Paradox By Elizabeth Maybury 60 years and some 23‚000 nuclear warheads later‚ since the bombing of Hiroshima‚ the question that faces the U.S and their allies alike “is less how a nation might array its nuclear forces and more how to stop the proliferation of nuclear weapons from spinning out of control”. The very nuclear weapons created to deter attack and ultimately bring about peace are also the cause for ambiguity among world nations‚ the hole in which millions of tax payers dollars
