So, we have a “clock” which starts ticking the moment something dies.Obviously, this works only for things which were once living.Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.

They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.

The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.

The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.

Radioisotope geochronology in its present form is made possible by radioactive decay.

Radioactive decay, also known as nuclear decay or radioactivity, is the process through which the radioactive (unstable) nucleus of an atom emits particles which lowers it to a lower energy state.
