Isotopes are different atoms of the same elements having the same atomic number but a different mass number. Isotopes of radioactive elements are found to be very useful in different fields like carbon dating, agriculture, medicines, the production of synthetic elements, etc. Important uses of radioisotopes are as follows. Estimation of Age of Rock and Bone Samples:. The radioactive uranium U ore is found with nonradioactive lead Pb.
Various Applications of Radioisotopes
Application of radioisotopes
This article throws light upon the various applications of radioisotopes in the biological science. Radioisotopes are frequently used for tracing metabolic pathways. This usually involves adding a radioactive substrate, taking samples of the experimental material at various times, extracting and chromatographically or otherwise separating the products. Radioactivity detectors can be attached to gas liquid chromatography or high performance liquid chromatography columns to monitor radioactivity coming off the column during separation. Alternatively, radioactivity can be located on paper or thin-layer chromatography with either a Geiger-Muller chromatograph scanner or with autoradiography.
Applications of Radioactive Isotopes
Radioactive isotopes have the same chemical properties as stable isotopes of the same element, but they emit radiation, which can be detected. If we replace one or more atom s with radioisotope s in a compound, we can track them by monitoring their radioactive emissions. This type of compound is called a radioactive tracer or radioactive label. Radioisotopes are used to follow the paths of biochemical reactions or to determine how a substance is distributed within an organism. Radioisotopes radioactive isotopes or radionuclides or radioactive nulcides are used in two major ways: either for their radiation alone irradiation, nuclear batteries or for the combination of chemical properties and their radiation tracers, biopharmaceuticals.
