Use of radioisotopes in carbon dating

Here are some example of the production of radioisotopes: Radioisotopes are frequently used in medicine, industry and agriculture for variety of useful purposes.

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

This is because humans that lack iodine in their diet will generally have problems with their thyroid, sometimes leading to an enlarged neck.

Materials that originally came from living things, such as wood and natural fibres, can be dated by measuring the amount of carbon-14 they contain.

For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.

Although there is a perception that radioactivity is generally deadly, radioisotopes have also provided us with many important advances in science, medicine, and technology.

Aside from carbon-14 dating, radioisotopes have had important consequences for medicine.Once an organism dies, it stops taking in carbon-14.The carbon-14 it contained at the time of death decays over a long period of time, and the radioactivity of the material decreases.Nuclei which do not emit radiations naturally are called stable nuclei.In general, most of the nuclei with atomic number 1 to 82 are stable nuclei.For example, uranium-238, having a half-life of 4.5 billion years, can be used to date rock formations.
