OSL properties for the fast component of quartz LM-OSL comparing natural and artificial irradiation relevant to dating.

초록

A comparative investigation for the fast component of quartz LM-OSL between a natural and an artificial dose was carried out. Using a mathematical peak deconvolution, the LM-OSL signal was separated and the related physical information was obtained. Three different luminescence groups were observed among the quartz samples in a comparison of the ratios of relative areas for fast components of a natural dose and an artificial dose. The ratios in group A were close to a value of unity, while those in group B and group C showed lower and higher values than unity, respectively. The relative ratios of sensitivity change for the fast component areas during each regenerative measurement were also classified for the above three groups. In addition, it was known that the sensitivity changes of each of the fast components from the natural and the artificial dose influenced the equivalent doses evaluated from the SAR method using the LM-OSL fast component.
