The single-aliquot regenerative-dose (SAR) protocol to the optically stimulated luminescence (OSL) was applied to measure the paleodose of ancient Chinese bricks with an age range from 180 to 1600 years. In the protocol

sensitivity changes can be corrected by using OSL response to a fixed test dose during measurement. For comparative study between OSL and TL

thermoluminescence (TL) measurement procedures were also applied to determine the paleodose of the bricks. Both results of OSL and TL are in good agreement with

and the paleodose ratios (DeOSL/DeTL ) are between 0.96 and 1.21

with a mean value of 1.08±0.07. The annual dose of the bricks

estimated by the paleodoses and the known ages

ranges from 5.07 to 6.85 mGy/a

comparable with the measured annual dose values. Therefore

it is concluded that the SAR protocol is a rapid and effective OSL technique to authenticate Chinese bricks.
