Abstract Objective According to analysis metrological verification results of detectors which dispersity are ±1% to verify whether thermoluminescent personal dosimeter called CTLD-J 4000 can be suitable for the place of radiolo-gical diagnosis and radiotherapy of different energy. Methods Under the "Thermoluminescence Dosimetry Syste-ms Used in Personal and Environmental Monitoring for X and Gamma Radiation JJG593 -2006", the preparing thermoluminescent personal dosimeter was taken to The first class metering station of ionizing radiation of Science and Technology Industry of National Defense for the verification, and the results were analyzed. Results The linearity and the en-ergy response of thermoluminescence dosimetry system meet the demand of test specification. Specific val-ue of detetors determined which in the different groove of personal dosimeter can differentiate photon of different energy, and only if choosing calibration factors scientifically, can the effective dose be calculated. Conclusion Thermo-luminescent personal dosimeter called CTLD-J4000 can be suitable for identifying energy, and can be used to monitor personal dose in the the place of radiolo-gical diagnosis and radiotherapy of different energy.
