Types of Radiation:

• List the three types of Radiation and describe conditions under which each case occurs.
Alpha, Beta, Gamma.
Alpha radiation/emission - Alpha particles are the nuclei of a Helium atom 42He. Consisting of two protons and two neutrons, positively charged.
The nuclei are ejected from heavy, unstable nuclei so as to remove excess protons and neutrons. However, the formed nuclei may still be radioactive in which even further decay will occur. Alpha emissions occur in nuclei with atomic numbers greater than 83. E.g 23892U  42He + 23490Th (both mass and No. of protons are conserved during the reaction)

Beta radiation/emission – Beta particles are electrons (0-1e) that have been released from the nucleus of a radioactive atom when a neutron decays into a proton and electron. Beta decay/emission happens when the neutron to proton ratio is too high due to excess neutrons. 10n  11p + 0-1e (mass is still conserved as well as number of protons.)

Gamma radiation/emission – Gamma ray emission can be found when either alpha or beta decay occurs. Gamma rays are high energy electromagnetic rays. Gamma radiation is just the excess energy of the reaction being shed off, gamma rays do not effect mass numbers or atomic numbers. 6027Co  6028Ni + 0-1e + y

As elements get heavier the ratio of neutrons:protons moves away from being 1:1, Bands of instability surround the band of stability showing where the neutron:proton ratios are either to great or too small,

• Discuss the half life of radioactive elements.
“The half-life of a radioisotope is the time required for half the atoms in a given sample to undergo radioactive decay; for any particular radioisotope, the half-life is independent of the initial amount of...

Uuq-292 lost 3 neutrons, and afterwards the resulting isotope decayed further by alpha emission. 24494Pu + 4820Ca  292114Uuq  289114Uuq + 3(10n), this claims that superheavy elements can be made in the laboratory.

Isotopes: Atoms of the same element (same atomic number) but with differing numbers of neutrons, different mass numbers.

Nuclear Energy and Nuclear Power outside of WWII Essay - Most people only know of the nuclear power that went to nuclear warfare and the bombs that were a part of World War II. However, nuclear has made a name for itself in the last seventy years or so. There are plants all over the country, most are east of the Mississippi, but there is quite a bit to the west as well. There is a total of one hundred in the country, the quad cities alone has two nuclear power plants. All over the world plants have been built, the world has seen what an asset nuclear energy can be....   [tags: Chemistry, Fission]

The Basics of Nuclear Weapons Essay - In order to fully understand how nuclear weapons work, it is crucial to first understand the basic atomic structure of an atom. The discovery and contribution of the atom formed the foundation of modern nuclear weapons. Along with that comes the generation of electricity through the use of nuclear power. A Greek dilettante by the name of Democritus was known to be the first to theorize the atom as the universal building blocks of all things during the fourth century B.C. He was amplifying an earlier notion by his mentor and philosopher Leucippus....   [tags: Physics, Chemistry, Atomic Energy]

Nuclear Power Plants and Earthquakes: Fukushima Essays - Nuclear Chemistry Project - Fukushima There are too few precautions that are taken when considering Nuclear Power plants and the dangers involved. People trust the regulations too easily. Some systems fail; there needs to be more safety features and backup systems/plans that are checked more regularly. Nuclear power is made by a nucleus absorbing a neutron. It then splits into nuclei that are lighter than the original nucleus. This process emits large amounts of energy in the form of heat. Fuel rods are long slender rods of zirconium that provides the reactor with fuel....   [tags: nuclear power, Tsunami, Japan]

Essay on History of Chemisty: Nuclear Power - ... Scientists Peierls and Frisch pushed the atomic bomb by writing a paper that gave the theorized amount of uranium it would take to make a bomb equivalent to several thousand tones of dynamite and even included how the bomb could be set off, what the effects of the radiation would be, and how the uranium could be produced. The Military Application of Uranium Detonation committee also known as MAUD was created and supervised the research at several universities that went into creating the atomic bomb....   [tags: fission, atoms, risks, people, radioactive] 1951 words

Ethical Implications of Chemical, Biological and Nuclear Warfare Essay - Ethical Implications of Chemical, Biological and Nuclear Warfare Thesis As current problems of terrorism and the war on Iraq, chemical, biological and nuclear warfare (CBW) issues are important and relevant. CBW agents are dangerous, uncontrollable and undifferentiating weapons of mass destructions. Chemical, biological and nuclear weapons are capable of mass destruction aimed at killing masses of people. Using CBW agents comes with many ethical dilemmas and consequential side-effects. Chemical, biological, and nuclear weapons are designed to yield a great number of deaths....   [tags: War Weapons Chemistry Ethics Essays]

This technique identifies unknowns but is fairly long in its reading along with mediocre accuracy, while showing many impurities; moreover, this technique is quite expensive in affording the actual NMR Spectroscopy equipment and requiring 2-50mg of solid sample to analyze, although recoverable.15 Near-Infrared Spectroscopy focuses on the near-infrared region of the electromagnetic spectrum, from about 800-2500nm, which analyzes molecular implication and vibrations.16 Although these transitions are prohibited by the quantum mechanics selection rules, the molar absorptivity in the near-IR region is typically small.17 This technique penetrates much farther into a sample than other types o...   [tags: spectroscopy, unwanted molecules] 1917 words

Essay about The Chemistry Times: Why I Want to Study It - To me, chemistry is an ever evolving field, like making a strand of nylon, it is always expanding. Chemistry is advancing at an inconceivable speed, with discoveries varying enormously from the structure of an atom to the synthesis of aspirin. One aspect of chemistry that I admire is that the content is not only supported by the theory but can also often be demonstrated practically, this is shown well when analysing rates of reaction, therefore providing a stronger understanding of the topic. The most fascinating part of chemistry is the transformation of raw materials into useful products and this is demonstrated extremely well by the reaction between 1,6-diaminohexane solution and decanedi...   [tags: theory, practically, reaction, transformation] 558 words
