Carbon dating equation calculator
Note that the half-life remains the same throughout the life of the sample.
As the activity of a sample is proportional to the number of radioactive nuclides present it is also possible to say that the half-life is the time taken for half of the radioactive nuclides in a sample to decay.
Carbon-14 is a radioactive isotope of carbon with a half-life of 5730 years.
All living matter takes in carbon-14 during its lifetime as it naturally occurs in nature.
Fractionation is the term used to describe the differential uptake of one isotope with respect to another.
The surface of the graphite is sputtered with heated, ionized cesium and the ions produced are extracted and accelerated in the AMS system.
