    Radioactive decay occurs when the nucleus discharges an abundance of energy, in the type of waves, causing nuclear instability which can occur naturally or spontaneously. Alpha (α), beta (β), and gamma particles (γ) are the most known types of radioactive decay despite the fact that there are some more. Alpha decay, α, composes of two neutrons and two protons making alpha particles similar the nucleus of helium. Large components, for example, uranium, radium, and thorium have a greater number of neutrons than they have protons which aids alpha decay to happen. At the point when another atom is made the mass number decreases by four and its atomic number by two after the core discharges an alpha particle which contains two less protons and neutrons. Right when another atom is made the mass number declines by four and its nuclear number by two after the center releases an alpha molecule which contains two less protons and neutrons. Unlike alpha decay, beta decay comes in two forms β+ and β-. The strategy in…

    Task 1: radioactive decay is a nuclei of some isotopes which are unstable. If a radioactive isotope decays the it will change and become a different atom with different number of protons. Radioactive decays also are a process which has an unstable atomic nucleus and which causes it to lose energy this because of radiation, for example there three main types of radioactive decay alpha, beta, and gamma particle. If a material has unstable nuclei it would be considered as radioactive. If an atom…

    Half-life Carbon dating is used to find the age of fossils, the earth, and rocks. 14C is an unstable isotope that causes radioactive decay. Because 14C causes radioactive decay, it is used in finding the age of organic matter, or the process of Carbon dating. Radioactive decay occurs when one element changes into another element as it decays. As 14C decays, it turns into 14N, an isotope of Nitrogen. Using the original amount of carbon in the organic material, and the half-life of carbon, 5,730…

    Collectively the pennies represent a radioactive sample, and each penny is an atom. Because each penny has a 50% chance of decaying it can represent a radioactive atom. When the atoms are grouped together it becomes a sample of a radioactive element. For the simulation to work one has to assume that a coin toss has a 50% chance of landing on heads and a 50% chance of landing on tails. If this is not true then the trial will not be a true half-life because more or less than half of the atoms…

    chemical compounds producing radioactive tracers. These radioactive tracers are sent into a patient’s bloodstream and accumulate in areas of high cellular activity, and the radiation given off by the tracers is picked up on a scan. This gives doctors an image of anatomic locations that may contain a tumour or other abnormal cellular activity, such as a fracture or arthritis. This is highly useful because these problems would often go untreated until much later in their development since they…

    Natalie Caparelli Mrs.Stanton October 5, 2015 Is Nuclear Chemistry Worth The Risk? Pros and Cons of Nuclear Chemistry in Medicine Nuclear chemistry, along with its advantages, has many cons such as extended decay periods, emission of radioactive particles into the atmosphere, and negative side effects from its many medical uses. Radioactive particles vary in strength, alpha particles, for example, are able to pass through sheet of paper. On the other hand, gamma rays are about to pass through…

    • 5 Pages

    In order to build a nuclear process, radioactive elements are combined with nuclear reactors. In order to identify which chemicals should be used for medical purpose, it is important to study the absorption and radiation of certain chemicals in living organisms. Nuclear chemistry is a vastly growing aspect of medicine and it is important to study the chemistry behind it in order understand its significance…

    Carbon Dating

    • 545 Words
    • 3 Pages

    Once a living thing dies, the carbon dating process begins. As long as an organism is alive it will continue to take in 14C or radio carbon; however, when it dies, it will stop. Since 14C is radioactive (decays into 14N), the amount of 14C in a dead organism gets less and less over time. Therefore, part of the dating process involves measuring the amount of 14C that remains after some has decayed. Scientists now use a device called AMS (don't know what it stands for) to figure out the ratio of…

    One example of a gastric emptying study is an operation that is done by nuclear medicine physicians using radioactive chemicals that examines how fast the food leaves the stomach and goes to the small intestine. Gastric emptying studies are used for checking patients who are experiencing signs of slow and, less commonly, rapid emptying of the stomach. Some signs to watch for are low energy levels, nausea, and heartburn. During a gastric emptying study, the patient eats a meal where the food in…

    Radioiodine production Radioiodine is defined as a radioactive isotope of the chemical element Iodine. Although there are at least 37 different Iodine radioisotopes, only four of them are used as tracers or therapeutic agents in medicine; these are 123-I, 124-I, 125-I, and 131-I, with the latter being the most common in clinical practice. Essentially all industrial production of radioiodine isotopes involves four aforementioned radionuclides. History of radioiodine production and usage The…
