How far back can you carbon date
As a tree grows, only the outermost tree ring exchanges carbon with its environment, so the age measured for a wood sample depends on where the sample is taken from. This means that radiocarbon dates on wood samples can be older than the date at which the tree was felled. Meer weergeven Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon Meer weergeven Samples for dating need to be converted into a form suitable for measuring the C content; this can mean conversion to gaseous, liquid, or solid form, depending on the measurement technique to be used. Before this can be done, the sample must be … Meer weergeven Interpretation A key concept in interpreting radiocarbon dates is archaeological association: what is the true relationship between two or more objects at … Meer weergeven History In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began … Meer weergeven The variation in the C/ C ratio in different parts of the carbon exchange reservoir means that a straightforward calculation of the age of a … Meer weergeven For decades after Libby performed the first radiocarbon dating experiments, the only way to measure the C in a sample was to detect the radioactive decay of individual carbon atoms.

The precision of a dating method depends in part on the half-life of the radioactive isotope involved. 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.
