This can be done very accurately, although some samples may be difficult to work with.

Beyond this, the accuracy of the date depends on the reliability of the assumptions used in interpreting the measurements (see below).

It is known that such variations have occurred, but it is thought they can be corrected for by comparing a sample’s C level with the standard curve constructed using samples of known age.

Another assumption is that the amounts of carbon-14 present in the geophysical reservoirs must be constant.

Violations in the atmosphere result from volcanic eruptions that occasionally add C.

Also, there is a lag time for atmospheric mixing in the northern and southern hemispheres which results in somewhat different ages for the two hemispheres.

In most cases, the three methods produced similar results.

Surprisingly, in at least one case the date range given by There may be other examples of systematic variation in isotope decay rates.

The earth’s sediments contain a vast amount of carbon-12 in the form of coal and oil. [14] Post WM, Peng TH, Emanuel WR, King AW, Dale VH, Deangelis DL. The amount of carbon in fossil fuels is estimated at 6,000 gigatons, and the amount of kerogens (organic) in sediments is about 15 million gigatons. Carbon-14 dating cannot be applied to materials that have no C dates are less than that figure.
