The conversion is finished by Keff-value, which is an effective or effectiveness. But the Keff can not be measured directly for each sample and only the external radiative efficiency K3.7 can be measured. In order to obtain the Keff a special study for the conversion factor of Keff to K3.t has been made using the ultrathin TLD. The results show that the conversion factor of tile TLD for archaeological samples is 0.847, which is in agreement with calculated value 0.85.展开更多

Twenty three samples, ranging in age from 200 to 9000 a,including multiple styles and shapes and drawn from diverse and remote areas in China have been used to establish the typical annual dose as 5.5mGy/a and its associated deviation. Ten unauthenticated samples are then appraised using the technique which,in nearly all cases, leads to satisfactory results.展开更多
