There are two components involved in evaluating age by luminescence.One is the “equivalent dose” determined from luminescence measurements on mineral crystals (usually quartz or feldspar) extracted from the material to be dated.At this point, the method seems to be a straightforward concept.However, problems arise from assuming a uniform radiation dose rate over any significant period of time and assuming that the TMRD resulted from the object or artifact being in a strictly constrained environment identical to that in which it was found.Therefore, luminescence dating results should be regarded with skepticism and the accompanying caveats clearly stated.Instead, we should trust the Word of the One who was there at the beginning as recorded in the book of Genesis.For example, a lithium fluoride crystal can preferentially respond to gamma thermal neutron, beta proton, or alpha particle radiation depending on whether it is constructed from The constancy of the RDR is even more problematic because it’s based on the uniformitarian assumption that the RDR has been constant.
The second protocol was developed more recently and is based on a thermoluminescence (TL) signal measured under isothermal conditions (termed the SAR-ITL technique).We investigate several experimental factors which affect the precision and accuracy of the two protocols.Luminescence dating techniques have been used extensively for archaeological and geological samples.Factors which influence the accuracy of the two components, and so the accuracy of the age, are discussed.Limiting factors are identified in order to recognize aspects of measurement on which future development must concentrate to achieve an improvement in accuracy of age determination.
One hundred random variants of the natural samples were generated by keeping the transition probabilities between energy levels fixed, while allowing simultaneous random variations of the concentrations of the 11 energy levels.
