How are radioactive isotopes used in absolute dating

Carbon-14, an isotope of carbon, is most commonly used in determining the age of formerly living things. Carbon-14's half life is approximately 5,700 years, making it perfect … for things like Egyptian mummies and other ancient organic artifacts.

Radiometric Dating and the Geological Time Scale

The internationally accepted radiocarbon dating reference is 95% of the activity, in 1950 AD, of the NBS oxalic acid normalized to d 13 C of –19.3‰ with respect to PDB. The factor of 0.95 adjusts the oxalic acid to the activity of wood from 1840 to 1860 (‘pre-industrial’). …

Carbon-14 - Wikipedia

Prior to the availability of radiometric dating, and even prior to evolutionary theory, the Earth was estimated to be at least hundreds of millions of years old . Radiometric dating has simply made the estimates more precise, and extended it into rocks barren of fossils and other stratigraphic tools.

Carbon-14, (14 C), or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam

Carbon-14 is a method used for young (less than 50,000 year old) sedimentary rocks. This method relies on the uptake of a naturally occurring radioactive isotope of carbon, carbon-14 by all living things.

Over time, less and less radiation from carbon-14 is produced. The amount of carbon-14 radiation detected for an organism is a measure, therefore, of how long the organism has been dead. This method of determining the age of an organism is called carbon-14 dating.

Carbon Dating: Why you cant trust it or other radiometric

The ratio used in Carbon 14 dating is Carbon 14:Carbon 12 + Carbon 13. The ratio in living organisms remains constant because organisms are constantly taking in carbon compounds that contain the same ratio of carbon-14 to Carbon 12 and Carbon 13 that is found in the atmosphere.

Carbon dating is based on the assumption that the amount of C14 in the atmosphere has always been the same. But there is more carbon in the atmosphere now than there was 4 thousand years ago. (1) Since carbon dating measures the amount of carbon still in a fossil, then the date given is not accurate.
