And finally, we must assume that there hasn't been any contamination in the specimen which we are attempting to date.Scientific research has called the first two assumptions into question.Radiocarbon dating estimates can be obtained on wood, charcoal, marine and freshwater shells, bone and antler, and peat and organic-bearing sediments.

In a major breakthrough, archaeologists have excavated from the ruins of Dwarka a wooden block that promises to solve the mystery about the exact age of the submerged city believedby many to belong to Lord Krishna.Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.As the name implies, relative dating can tell which of the two artifacts is older.Carbon dioxide is distributed on a worldwide basis into various atmospheric, biospheric, and hydrospheric reservoirs on a time scale much shorter than its half-life.Measurements have shown that in recent history, radiocarbon levels have remained relatively constant in most of the biosphere due to the metabolic processes in living organisms and the relatively rapid turnover of carbonates in surface ocean waters.
