The absorbed dose in quartz samples irradiated by β rays in TL or OSL dating protocol was simulated using the EGSnrc /DOSRZnrc code.Effects of thickness and grain size of the quartz samples on the absorbed dose were evaluated with the samples of Φ0.97 cm×(10–500) μm
in grain size of 60–300 μm.The results show that the absorbed dose in quartz is relative to the sample thickness
and the maximum difference of the relative dose can be up to 10%.The absorbed dose is relative to the grain size
too.The relative dose increases with decreasing grain size
and the maximum difference can be up to 19%.These factors should be considered in the dating.
