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…
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…
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…
Most individuals with even the most rudimentary knowledge of science have probably heard of x-rays and gamma radiation. Very few however, will be able to tell you where these forms of radiation come from. The answer: Pulsars. Pulsars, or neutron stars, are physics sandboxes that provide extreme conditions for humans to experiment with which are not readily available on Earth. Due to this usefulness, the discovery and research of these phenomena should be of the utmost importance. These neutron…
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 radiation was found by having no sources of radiation involved and left the counter running, the value of background radiation was found to be (0.54±0.03) counts per second.…
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…
Handling Nuclear Wastes: On one hand Nuclear energy seems to be a sustainable way forward, not emitting greenhouse gases and producing far less waste material. On the other hand, it is not truly green; it involves mining, recycling and refining of radioactive waste…
equipment that is used are radioactive and very dangerous if it comes in…
Paragraph 1 The structural evolution of FePO4 studied from a temperature range of 294K to 1073K by neutron powder diffraction. It is unique from α-quartz isotopes. It is different because it’s a cation is a transition metal. The structure dimensions and atomic coordinates in the α phase tend to increase by great amounts as the high-temperature β-phase rises and exhibit first order transition at 980K. The atomic structure dimensions of the α-phase FePO4 increased in a non-uniform pattern with…
The first woman to win a noble prize for not just Physics but Chemistry too, would have a dramatic impact on the world as we know it today. Marie Salomea Sklodowska was a polish scientist, born on November 7, 1867 in Warsaw, Congress Kingdom of Poland, Russia. Marie’s mother, Bronislawa, and father, Wladyslaw, were both teachers and wanted Marie to have an education. During school when Marie became fascinated with the art of science Marie’s parents were extremely encouraging and supportive.…
