Pre-dose method normally requires several times of artificial doses been added to the sample (test dose or calibrated dose) to process the thermo-activation

thermoluminesence and quenching effect. The error of the measurement usually increases with multiple procedure and dose adding (about 20%-30%). In order to increase the accuracy of the dating

this article selected a constant dose value as a reference of thermoluminesence and quenching effect. Using different testing procedures to evaluate the change in luminous intensity (sensitivity) by a set of mathematical equations. The best testing procedures are selected to minmize the error. The error can be reduced to almost 10% which is much better than the original dating method. The testing method is feasible but further works are necessary to testify

the conclusion.
