Important applications of radioisotopes are as under –
- Radiocarbon dating – its a method by which the age of fossil wood or animal is determined using C-14 isotope.
- Study of chemical reactions – the nature of some chemical reactions can be studied by mixing a radioisotope with a nonradioactive isotope of the reactants. The radioisotope used for this purpose is radiotracer.
- Diagnosis – Radioisotope is found very useful to diagnose and understand many diseases.
