%X 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 s£¿o 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.
