The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.
Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

The purpose of these travels during the Bronze Age was related to trade and the transportation of pure copper from Lake Superior of Canada.” According to his findings it seems that after the first Minoan merchants, the Mycenaeans continued the journey, and, as reported by Plutarch, they sent Hercules to revitalize the presence of the Greek element, which had been diminished by the continuous miscegenation with the locals.
Later, during the Iron Age, the interest in the region declined and until the Hellenistic time, it remained only as a conventional ceremonial tradition.
This definition confirms that the island of Greenland must be identified with the underworld, where Cronus had been buried in a cave and was being kept there by Zeus. The reason for these long journeys during the Bronze Age is documented by the pure copper, which was found in large quantities in the region around Lake Superior and the island Royale, both located in Canada.
From this area, about 50,000 tons of copper were mined between 2400 BC and 1200 BC. During the time of Plutarch, as he states himself, they did not carry copper but golden cups and urns, inside which they kept the provisions for the journey. Finally, it is known that in the ancient times the Oracles were centers where they kept chronicles of geographical knowledge, and as a result they gave advice about the future colonization.
It may sound unbelievable but a Greek-Canadian scientist is stating that the Ancient Greeks may have reached America years before the Spanish Seafarer Columbus did. Minas Tsikritsis, in the text by Plutarch “On the Apparent Face in the Orb of the Moon,” in paragraphs 941A-942, claims that he has identified and demonstrated through computer programs the restoration of a forgotten historical reality, which had until now eluded many researchers.
In the study, he indicates that the prehistoric Greeks knew that “west of the three islands and northwest of Britain” there was a “great” continent. Mariolakos, identified the great continent, surrounding the great Ocean, as today’s North America. Tsikritsis states that, “even before the time of Christopher Columbus, there was a communication which began during the Minoan era and continued until the Hellenistic times.
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 idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.
