This paper presents the results of TL and OSL dating of soil and fragments of bricks from a grave, which was occupied by two mummified nuns, found at "Luz" Monastery, located in the state of São Paulo, Brazil. The TL and OSL ages were compared to C-14 dating ones obtained from bone collagens of the mummies. The majority of the ages is related to the eighteenth century. The gamma-ray spectroscop...

thermoluminescence (tl) dating was established in oxford to fulfil the demand for dating ceramics and other heated man made products (aitken, 1985).  it determines the time elapsed since the mineral grains have been heated. following the establishment of tl dating method, it was used to date fired materials such as pottery, flint and etc. optically stimulated luminescence (osl) determines the t...

The quest for new materials thermoluminescence (TL) and optically stimulated luminescence (OSL) dosimetry continues to be a central line of research in dosimetry, occupying many groups investigators, is the topic publications. Nevertheless, it has also been area with pitfalls, slow advances our understanding processes, rare improvements over existing materials. Therefore, this paper reviews sta...

در این کار پژوهشی، نمونه‌های هیدروکسی اپتایت آلاییده با ناخالصی‌های سریم، گادولونیم و ترکیبی از دو ناخالصی به روش هیدروترمال سنتز شدند. منظور بررسی فازهای بلوری تشکیل یافته هرکدام شده، کد MAUD که یک نرم‌افزار برای تجزیه تحلیل ساختار ماده استفاده پراش بر اساس ریتولد است، شد. پاسخ دزیمتری ترمولومینسانس نمونه‌ها مورد قرار گرفت یافته‌ها نشان داد نمونه‌ ترکیبی، سطح میانی است. مشخص شد افزودن سریم می‌...

This study utilizes OSL-SAR, TL-SAR, and TL-MAAD methods to date heated quartz extracted from burnt clay pottery samples the Lingjiatan archaeological site, China. The OSL components of were determined by deconvoluting CW-OSL curve, Fast Ratio value was used distinguish whether initial signal dominated fast component. results show two types characteristics in signals: Type I is component (Fast ...
