    Radioactive isotopes (radioisotopes) are isotopes which are atoms of the same element that are chemically identical but vary in the number of neutrons they contain. Radioactive isotopes can participate in reactions just like non radioactive elements. Autoradiography is a technique used to trace the movements of certain substances around plants. An example of this is carbon 14. Carbon 14‚ a radioactive isotope‚is added to the carbon dioxide supply of the plant‚ to study the movement of products
