摘　　要：目的建立用现场石英材料进行突发事件和核事故剂量重建的有效方法,这种方法也可用于辐射流行病学研究中的剂量重建。方法利用石英材料的热释光特性,通过样品制备、剂量学性能和刻度方法研究,建立这一剂量重建新技术。结果得出了现场石英材料的主要剂量学性能,建立了石英样品的制备和刻度方法。结论本报告中的方法在突发事件和核事故现场的剂量重建中是一种很有意义的技术,现场采集方便,TLD测量简单,但样品的制备程序需要严格控制。Objective To develop a feasible method of dose reconstruction with quartz TLD for nuclear accident dose reconstruction. Methods To prepare samples of quartz for TLD measurement, analyze the pre - dose characteristic of the quartz TLD, and establish a dose calibration method of the quartz TLD. Results The main information of pre - dose characteristic of the quartz TLD and have been obtained the methods of sample preparation and dose calibration of quartz TLD established. Conclusion The method is very significant in nuclear accident dose reconstruction. It is very easy to collect sample from a nuclear accident locale and to have TLD measure, but quality control is necessary in the sample preparation.
