Nuclear Medicine Essay -- nuclear medicine medical

Nuclear medical specialty is the use of radioisotopes for diagnosis, treatment, and research. Radioactive chemical tracers emit gamma rays which provides diagnostic selective information to the highest degree a persons an specky and the functioning of specific organs. Radioisotopes argon in addition utilizes in treatments of diseases such as cancer. It is estimated that approximately one in twain people in Western countries are likely to experience the benefits of atomic medicine in their lifetime.To understand what a radioactive isotope is a staple fibre understanding of the atom is necessary. Atoms are comprised of three subatomic particles protons, neutrons and electrons. Protons and neutrons bind unneurotic to form the heart and soul of the atom, while the electrons surround and orbit the nucleus. Protons and electrons have antagonist charges and therefore attract one another (electrons are negative and protons are positive, and opposite charges attract), and in most cases the number of electrons and protons are the uniform for an atom (making the atom neutral in charge). The neutrons are neutral. Their purpose in the nucleus is to bind protons unneurotic. Because the protons all have the same charge and would naturally snub one another, the neutrons act as glue to hold the protons tightly together in the nucleus.While all atoms of the same component have the same number of protons, it is possible for atoms of one element to have different numbers game of neutrons. Atoms of the same element with different numbers of neutrons are called isotopes . For example, all atoms of the element speed of light have 6 protons, but while most carbon atoms have 6 neutrons, some have 7 or 8. Isotopes are named by giving the name of the element followed by the sum of the neutrons and protons in the isotopes nucl... ...why does the technologist step behind a shield to prevent moving picture to themself? The ray dose for each exam is relatively small, but e preciseplace time, the dose can add up. There are many pass on and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist moldiness follow strict precautions to keep their cumulative exposure to a minimum.Although no adverse health effects have been directly linked to low-dose radiation exposure, the medical community is playing it safe with regards to radiation. Most physicians are very careful about ordering radiologic tests. They should not order a canvass unless it will improve patient care. If you have a question about the importance or the necessity of a radiologic test that has been ordered for you, be sure to ask your physician.
