Part 5 Potassium-argon, uranium-series, fission tracts. Part 6 Luminescence dating: thermoluminescence (TL); paleodose and annual dose; on-site procedures; laboratory measurements - Alpha counting, Beta TLD, alkali feldspar - the isochron technique, zircon dating; accuracy and error limits, date citation, age range; authenticity testing; beyond pottery - burnt flint, burnt stones, unburnt materials - calcite, shell, bone and teeth; optical dating - dating of mineral fractions from Viking pottery fragments, dating of the church of Santa maria Foris Portas, Lombardy, Italy.
Part 7 Electron spin resonance (ESR): radioactivity and annual dose; applications - stalagmitic calcite, travertine, tooth enamel.
Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope C.
This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.
The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.
The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.
This has created problems for radio carbon dating older than 4000 BP Before Present.…
Today I think most archeologists would argue that there is no direct archeological proof that Abraham, for instance, ever lived.…continue reading » Biblical Archaeological Review, March/April, 1990, 57.
This method is based on the fact that when a material is heated or exposed to sunlight, electrons are released and some of them are trapped inside the item.
