    Other isotopes are used by geologists to date older material.Each radiocarbon date has a statistical probability shown by the ± number.They proved this by showing that C-14 dates of wooden artifacts with cartouches (dated royal names) did not agree. Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.Carbon-14 has a half-life of 5,730 ± 40 years— during the succeeding 5,730 years.Radiocarbon dating has had an enormous impact on archaeology around the world since it made it possible to date carbon and wood could be directly without dependence on characteristic artifacts or written historical records.
