Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age, and the beginning of the Neolithic and Bronze Age in different regions.In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research.The section of the calibration curve for the 14C age of the Habakkuk Commentary is complex, so that the 14C age of 2054 cuts through a few spikes on the curve, providing two date ranges.

The table orders them chronologically, based on 14C age.

Many of the date ranges provided are actually two date ranges, for example the Habakkuk Commentary (#13), which is given as 160-148 or 111-2 CE.

The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.

The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

The second test (#21) yielded a result (50 BCE-130 CE) that was deemed more satisfactory.
