Nuclear medicine

In nuclear medicine, the diagnostic techniques use a radioactive tracer which releases gamma rays within the body. These tracers are usually isotopes that have a short life and are associated with some chemical compounds which allow certain physiological processes…

are just a few of the scans that were formed, thanks to the nuclear medicine of today. In 1896, a man by the name of Henri Becquerel discovered that uranium penetrating rays were similar to X-rays. This leads to other numerous discovers like the finding of elements polonium and radium, to the cyclotron invented by Ernest Lawrence that included the ability to produce radioisotopes of different elements. This leads to 1946, where the nuclear reactor in Oak Ridge, U.S. , was opened for…

Medical Aspect of Nuclear Chemistry Nuclear chemistry is a growing subfield of chemistry. Although it has also has been 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,…

are able to identify problems in the body earlier, allowing treatment to begin sooner and potentially turning a fatal disease into a chronic one. One area of technology that has proven to be very useful in medicine is the use of radioisotopes.…

Radiation is often seen by individuals as a substance that is rare and uncommon. Others believe that it only comes from nuclear bombs. However, that isn’t the case. It is found in everything from the soils that people walk on every day, to the walls and floors inside their homes. There’s radiation found in food and water that are consumed by people on a day-to-day basis. It is found within the gases inside the Earth’s atmosphere, and from cosmic rays from space ("Radiation in Everyday Life").…

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…

PET is a nuclear medicine, working imaging ability that creates a three-dimensional image of functional processes within the human body. [1] First, chemicals which emits gamma radiation are injected into the human body, then; the system detects pairs of gamma rays emitted indirectly by a tracer to show images of bones and organs. These substances are injected into the body, and are usually tagged with a radioactive atom.[1] Doctors use this device to create images of bones and organs of the…

Iodine is a metallic grey element found in the halogen part of the periodic table. In the early 1900s, many people in the U.S. were suffering from Iodine deficiencies which caused all sorts of health complications. The decision to add iodine to salt was made to remedy these deficiencies and the problems associated with them. Salt was picked as a host for the iodine, because of its widespread use and the ease at which iodine could be added. This decision did not come without a cost and today the…

therapeutic methods, physicians began testing the effects of the new elements in humans. Pioneering the experiments on human subjects in the field of nuclear medicine, Frederick Proescher used the knowledge from his predecessors to advance the medical use of radioactive materials. Changing the way that science understood the evolving field of nuclear medicine, Proescher became one of the first scientists to use radium for medical purposes. The medical experiments with radium allowed science to…

Each year, roughly 25 million procedures are carried out using technetium 99m (Tc-99m) and around 80% of all nuclear medicine procedures involve Tc-99m. (IAEA, 2008). However, many people don’t realise that our advancement into this modern age of radioisotopes is all thanks to the radioactive element uranium. First used to produce the destructive Hiroshima bomb during World War 2, uranium is now used to create the commonly used radioisotope Tc-99m and many other radioisotopes. Tc-99m is used in…
