Abstract Objective To provide a feasible method of dose reconstruction in radiation accident or in the epidemiological studies.Methods Ceramics materials (red bricks) which can be collected from the accident field were taken as samples, then quartz particles were abstracted from bricks, dose estimations using the pre-dose thermoluminescence technique were performed to simulated radiation accidents and the result of the estimations were compared with the actual radiation dose.Results The dose estimations using the pre-dose technique have shown a high accuracy.Conclusion A kind of dose reconstruction method is preliminarily established which accident field materials are used as samples, and the important factors which have a effect on the measurement were discussed.
