Radioisotopes have found extensive use in diagnosis and therapy and this has given rise to a rapidly growing field called nuclear medicine. Backgrounder on Medical Use of Radioactive Materials. Used for radiotracer technique for identification of sources of soil erosion and deposition as well as in density and fill height level switches.

In a metabolic study one or more of isotope tracers are infused into the body intravenously and then samples are frequently collected from which relative concentrations of. The specific isotopes used depends on the particular organ or body system being studied for example Xe. A NaI Tl detector placed flush with an individuals thyroid is used to detect any uptakes of radioactive iodine 123I 125I or 131I in experimenters using a volatile form or.

Archaeologists also use radioactive substances to determine the ages of fossils and other objects through a process called carbon dating. Copper-64 is used in the diagnosis of Wilsons disease and the assessment of renal perfusion whereas iodine-124 is used as a radiotracer in the body. Used especially for melanoma breast cancer and.

Radionuclides used in nuclear medicine procedures have short half-lives. Used in TAT for cancers or alpha radioimmunotherapy with decay products Bi-212 1 h and Po-212 03 µs delivering the alpha particles. For example technetium-99m one of the most common medical isotopes used for imaging studies has a.

12 primary and secondary liver. This is generally done via the process of isotope ratio mass. Gadolinium alloys are used in the production of magnetic and electronic devices such as video recorders.

The Radioactive isotopic materials are very essential in curing many dreadful diseases like AIDS cancer and Alzheimers disease. Although they do not emit radiation their unique properties enable them to be used in a broad variety of applications including water and soil management environmental studies. These are commonly employed as control rods in nuclear power.
