Thermoluminescence dating versus radiocarbon dating
For periods or areas for which no textual evidence is available, relative chronologies have to be established and these are mostly based on pottery sequences and typology.
A sequential ordering that places cultural entities in temporal, and often spatial, distribution.Precision is difficult to estimate and varies with the type of sample.SYNONYMS OR RELATED TERMS: geological dating CATEGORY: technique; related field DEFINITION: The study of earth history by correlating archaeological events to the timing and sequencing of geological events.Without nuclei, we simply would not exist, and it is important to understand why!NUPEX provides a free database of knowledge, created and maintained by expert nuclear physicists from all over Europe.This produces electrons and other charge-carriers (holes) which become caught in traps in the crystal lattice.
Heating of the pottery causes the electrons and holes to be released from the traps, and they recombine in the form of thermoluminescence.
It involves the collection of dates or successive datings establishing the position in time of a series of phenomena such as the phases of a civilization or the events of the history of a state.
A chronology is relative/floating when only the order of a succession of facts is known, but not their dates, and absolute when the opposite is true.
SYNONYMS OR RELATED TERMS: thermoluminescence dating, thermoluminescent dating; TLCATEGORY: technique DEFINITION: Chronometric method of dating ceramic materials by measuring the stored energy created when they were first fired.
It is based on the principle that ceramic material, like other crystalline non-conducting solids, contains small amounts of radioactive impurities such as potassium, uranium, and thorium, which emit alpha and beta particles and gamma rays causing ionizing radiation.
Plus, the site is extremely easy to use, to encourage pupils to explore the information here on their own.
