Radioactive decay

Over the last few decades technology has made great progress in the medical field, helping to discover new treatments and cures for problems affecting the human body. Anti-biotics are being used to fight off infection, multiple radiation beams are being used instead of just one for tumor treatment to help patients avoid harmful radiation, and many more that were thought impossible just a short while ago. But even in cases where there is still no definitive cure, technology has advanced so much…

used for the destruction of humanity in history this paper discuss on how it has been helpful through medical aspects. Nuclear chemistry is related with radioactivity, nuclear processes, and properties. 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…

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 the meal and the drink in the meal are combined with a little radioactive material. Then a…

age but it was found after years of searching and studying. Through radiometric dating we’re able to calculate the age of radioactive elements such as Uranium. But that’s not the only way they calculated the age of the Earth. They used carbon dating which uses carbon to calculate the age of plants and animals, including ancient organisms. Once dead these organisms over time decay and some fossilize after millions of years. In the documentary they used many methods to determine the age of the…

GM tube to detect radiation coming from a source. This is done by the decay particle ionizing and causing the charge to build up in the tube, which is discharged and the discharge is counted by the counter and added to a display. The GM tube must be calibrated at the best voltage so that the count rate is independent of the voltage. A test was done to find this value by changing the voltage and taking the counts using radioactive source, the value was found to be 860 volts. The background…

I n 1898, the radioactive elements Radium and Polonium were found by Marie and Pierre Curie. Thus the concept of treating cancers was born. The Curie’s work on radiation led to the possibility of cancer treatment, but also provided a better understanding of the atom. That is that an atom has a nucleus at its centre with surrounding energy shells which consist of negatively charged electrons. The electron was discovered in 1897 by J.J. Tomson, and was the first proved element of the atom. The…

Does Radioisotopes more harm than good Radioisotopes are isotopes of an element, which are radioactive. Radioactivity is a spontaneous transformation of an atomic nucleus accompanied by energetic radiation. In this process the radioactive atomic nucleus also known as the mother nucleus transform into a daughter nucleus that may belong to another element. This daughter nucleus will often be radioactive and decay to a new daughter nucleus until it ends up with a stable nucleus. Isotopes are…

Method In this LAB we measured how long it would take for varying starting amounts of M&M’s to decay. We did this LAB in order to find out if the rate of decay is dependent upon the initial amount of mass present in a radioactive sample. We changed the starting number of M&Ms or the initial “mass” of the M&Ms (our independent variable) in order to be able to come with a clear answer to the question. We also controlled the number of times we would shake the cup in order to not change the way we…

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…

with a heavy nucleus (often of a previously made transuranic element) target. The transuranic elements have short half-lives as the atomic number increases. The smaller nuclei combines within the target nucleus, creating a new unstable nuclide or radioactive isotope. The high speeds are required to overcome the large electrostatic repulsion between the small nucleus and the target nucleus since both are positively charged. This high velocity can be achieved in a particle accelerator by the use…
