IB SL and HL Chemistry: Discuss the uses of radioisotopes.
As a part of the medical subspecialty of Nuclear Medicine, various diagnostic procedures make use of Is there any way to change the half-life of a radioactive tracer? of nitrogen nuclei in the atmosphere which is the basis for carbon dating. Carbon nuclear medicine: Another isotope, carbon, is useful in studying Carbon, which is radioactive, is the isotope used in radiocarbon dating and. A useful application of half-lives is radioactive dating. This stuff is important to know when using radioactive isotopes as medical tracers, which are taken into.
Radioactive tracer - Wikipedia
Therefore the characteristic property of the radioisotope, namely its radioactivity can act as a tag or label, which permits the fate of the element or its compound containing this element to be traced through a series of chemical or physical changes. Some of the application of tracer techniques are discussed below.
Agriculture- To see how plants utilize a given fertilizer a solution of phosphate containing radioactive 32P is injected into the root system of a plant. Since 32P behaves identically to that of 31P a more common and non-radioactive form of the element, it is used by the plant in the same way.
A GM counter is then used to detect the movement of the radioactive 32P throughout the plant. Medicine- In medicine specific isotopes are used to observe the condition of specific organs. For example, a small amount of I is injected into the patient and kidneys are scanned with a radiation counter in the case of blocked kidney. Industry - Radioisotopes are commonly used in industry for checking blocked water pipes, detecting leakage in oil pipes etc.
If there is leakage at a particular place, the radiation detector will show activity at that particular place. Radioactive Carbon Dating Radioactive dating is used in determining the age of a dead tree or for that matter any dead organic matter. Carbon has a half-life of years. It is not used as a tracer, though its presence in living organisms, including human beings, can be characterized by measurement of the gamma rays.
The most widely used is 67Ga for gallium scans. An extensive list of radioactive tracers used in hydraulic fracturing can be found below.

Radioactive tracers are also used to study lipoprotein metabolism in humans and experimental animals. The urea breath test for helicobacter pylori commonly used a dose of 14C labeled urea to detect h. If the labeled urea was metabolized by h. In recent years, the use of substances enriched in the non-radioactive isotope 13C has become the preferred method, avoiding patient exposure to radioactivity.
