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.
