Social and academic controversy recently arose in response to the argument that Jeungdogaja (證道歌字), the metal type produced in Koryo, might be an earlier product than Jikjisimgyeongyojeol (直指心體要節), conventionally believed to be the first metal type ever manufactured, dated to 1377 A. The said issue of the metal types was preceded by a heated debate as to the authenticity of an art piece, Bbalraeteo (the Wash Place) painted by Park Su-geun, which was aucauctioned at KRW 4.5 billon, the highest price for an art auction in Korean history. In this context, the cultural and art historical importance and its associated monetary value have fuelled the row regarding when the object was manufactured and in what way the year of the piece’s production could be scientifically confirmed. This may be a solid-state detector or a device based on the gridded ionisation chamber.The latter type of detector can measure both the total energy of the incoming ion, and also the rate at which it slows down as it passes through the gas-filled detector.
In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates (coins and written history).In addition, this paper will consider the issues to develop the extensive applications of absolute dating to archaeological studies. Artefacts and features show three-dimensional attributes: time, space and form. These two pieces of information are sufficient to completely identify the ion as C atoms at the rate at which they decay.This requires sufficient atoms to be present to provide a large enough decay rate, as described above.
