Radioactive isotopes used for dating

The radioactive decay process of each type of radioisotope is unique and is measured with a time period called a half-life.
When they die no new carbon-14 is taken in by the dead organism.It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.Radioisotopes are widely used in medicine, industry and scientific research, and new applications for their use are constantly being developed.
