| Abstract: | [Objective]To ensure the accuracy of TL individual dose data about radiation workers,and evaluate the uncertainty in TL individual dose measurement. [Methods]The source of uncertainty was analyzed by calculating the given uncertainty. [Results]Relative expanded uncertainty was 8.2%. [Conclusion]The TL individual dose monitoring measurement uncertainty are influenced mainly by the scale factor,the repeatability of the detectors and the deviation of the optical system. |
