Several factors affect radiocarbon test results, not all of which are easy to control objectively.

Carbon dating is based on the loss of carbon-14, so, even if the present amount in a specimen can be detected accurately, we must still know how much carbon-14 the organism started with.

As samples get older, errors are magnified, and assumptions can render carbon dating all but useless.

For example, variations in greenhouse effects and solar radiation change how much carbon-14 a living organism is exposed to, which drastically changes the “starting point” from which a radiocarbon dating test is based.

For example, a steel spearhead cannot be carbon dated, so archaeologists might perform testing on the wooden shaft it was attached to.

This provides good information, but it only indicates how long ago that piece of wood was cut from a living tree.
