Which radioactive element is used in radioactive dating
The nuclei may degenerate at any period, which is known as the half life.
While the half life varies from element to element, it provides a good probability of the life of a radioactive element.
Recall our discussion earlier about the fission process in the making of a radioisotope.
Nuclear power stations use uranium in fission reactions as a fuel to produce energy.
Steam is generated by the heat released during the fission process.
It is this steam that turns a turbine to produce electric energy.
Carbon-14, an isotope of carbon, is most commonly used in determining the age of formerly living things.

Carbon-14's half life is approximately 5,700 years, making it perfect for things like Egyptian mummies and other ancient organic artifacts.However, the crater number relation must be calibrated against something with a known age.To measure the passage of long periods of time, scientists take advantage of a regularity in certain unstable atoms.Sterilization of medical instruments and food is another common application of radiation.By subjecting the instruments and food to concentrated beams of radiation, we can kill microorganisms that cause contamination and disease.Radioactive element includes technetium, which has the most stable isotope and what is estimated as the longest half-life.The least stable element is ununoctium, which has a half-life of 1.8 milliseconds.Or you can tell that certain parts of the Moon's surface are older than other parts by counting the number of craters per unit area.The old surface will have many craters per area because it has been exposed to space for a long time. If you assume that the impact rate has been constant for the past several billion years, then the number of craters will be proportional to how long the surface is exposed.Answer elements with a nonstable isotope or at least one naturally occurring isotope that is radioactive. There are a lot of radioactive elements: Technetium, Promethium, Polonium, Astatine, Radon, Francium...There are many practical applications to the use of radioactivity/radiation.
