Resumen

TUDELA, Diego R.G. et al. TL, OSL and C-14 dating results of the sediments and bricks from mummified nuns' grave. An. Acad. Bras. Ciênc. [online]. 2012, vol.84, n.2, pp.237-244.  Epub 08-Mayo-2012. ISSN 0001-3765.  http://dx.doi.org/10.1590/S0001-37652012005000031.

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 spectroscopy was used to evaluate natural radioisotope concentrations in the samples, and by using these concentrations the annual dose rates, from 3.0 to 5.3 Gy/kyr, were obtained. Neutron activation analysis was performed and the radioisotope contents results are in agreement with those obtained by gamma-ray spectroscopy. The contents of U, Th and Ce elements were higher than those found in usual sediments.

Palabras clave : dating; Thermoluminescence (TL); Optical stimulated Luminescence (OSL); Mummified Nuns; Mosteiro da "Luz".
