Radioisotopes used for dating
One example of a diagnostic application is using radioactive iodine-131 to test for thyroid activity (Figure 15.4 “Medical Diagnostics”).The thyroid gland in the neck is one of the few places in the body with a significant concentration of iodine.Chemotherapy is also a way in which radioisotopes are used in medicine.Radioisotopes emit radiations and although most of the time radiation is bad for your body cause it can encourage mutation and damage body cells but sometimes if used in controlled condition they can kill cancerous cells which is good Radioisotopes emit radiation, which can be used for a number of therapeutic purposes, mostly in the radiotherapy treatment of cancer.Scientists were also able to use radiocarbon dating to show that the age of a mummified body found in the ice of the Alps was 5,300 y.
Technetium-99 can also be used to test thyroid function.In addition radioisotopes can be used for diagnostic purposes, such as the use of radioiodide to trace thyroid absorption and…Radioactive isotopes have a variety of applications.Many people still cling to a different notion, despite the scientific evidence.
The radiation emitted by some radioactive substances can be used to kill microorganisms on a variety of foodstuffs, extending the shelf life of these products.
For example, if a rock is analyzed and is found to contain a certain amount of uranium-235 and a certain amount of its daughter isotope, we can conclude that a certain fraction of the original uranium-235 has radioactively decayed.
