Radioactive isotopes used for dating

The results showed that Ötzi died over 5000 years ago, sometime between 33 BC. Uranium has a very long half-life and so by measuring how much uranium is left in a rock its approximate age can be worked out. Radioactive isotopes have a variety of applications.Radioisotopes are widely used in medicine, industry and scientific research, and new applications for their use are constantly being developed.

By measuring the amount of carbon-14 left in dead organic material the approximate time since it died can be worked out.Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
