Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.

Uses of radioisotopes carbon dating video

Aside from carbon-14 dating, radioisotopes have had important consequences for medicine.

Iodine-131 has been used for treatment and detection in the system of thyroid disorders.

Specifically, since uranium-238 decays to form lead-206, comparing the amounts of uranium-238 to lead-206 can be used to determine the actual age of a rock.

These are only some of the many applications of radioisotopes in our modern-day world.

Then, watch the video lesson to learn more about radioisotopes.

It was discovered in 1934 by Grosse as an unknown activity in the mineral endialyte. This half life has later been re-determined by Godwin. Libby recognized that due to its occurrence in natural materials, either by simple mixing processes or by carbon exchange.

Radiometric dating is also used to date archaeological materials, including ancient artifacts.

Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
