The procedures used to isolate and analyze the parent and daughter nuclides must be precise and accurate.

This transformation may be accomplished in a number of different ways, including alpha decay (emission of alpha particles) and beta decay (electron emission, positron emission, or electron capture).

For instance, carbon-14 has a half-life of 5,730 years.

After an organism has been dead for 60,000 years, so little carbon-14 is left that accurate dating cannot be established.

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

The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

The temperature at which this happens is known as the closure temperature or blocking temperature and is specific to a particular material and isotopic system.
