This is the clock that permits levels of c14 in organic archaeological, geological, and paleontological samples to be converted into an estimate of time.The measurement of the rate of radioactive decay is known as its half-life, the time it takes for half of a sample to decay.Any organic material that is available in sufficient quantity can be prepared for radiocarbon dating.Modern AMS (accelerator mass spectroscopy) methods require tiny amounts, about 50 mg.Working with several collaboraters, Libby established the natural occurrence of radiocarbon by detecting its radioactivity in methane from the Baltimore sewer.In contrast, methane made from petroleum products had no measurable radioactivity.The ensuing atomic interactions create a steady supply of c14 that rapidly diffuses throughout the atmosphere.Plants take up c14 along with other carbon isotopes during photosynthesis in the proportions that occur in the atmosphere; animals acquire c14 by eating the plants (or other animals).

Carbon-14 is produced in the upper atmosphere when cosmic rays bombard nitrogen atoms.Many laboratories now use liquid scintillation counters with the samples being converted to benzene.All of these counter types measure the C-14 content by monitering the rate of decay per unit time.Bases may be used to remove contaminating humic acids.

Some types of samples require more extensive pre-treatment than others, and these methods have evolved over the first 50 years of radiocarbon dating.The collagen fraction usually yields more reliable dates than the apatite fraction (see Dates on bones).In addition to various pre-treatments, the sample must be burned and converted to a form suitable for the counter.Pre-treatment seeks to remove from the sample any contaminating carbon that could yield an inaccurate date.
