摘　　要：介绍了电晕法制备的驻极体在电离辐射 γ射线剂量测试中的应用 ,重点介绍了驻极体的电晕法制备装置和驻极体剂量测试装置的设计制作 ,描述了剂量测量装置的感应电流法工作原理、结构和特点 ,说明了这些特点对准确测量辐射剂量的重要性 ,给出了电晕法制备驻极体的电荷稳定性及辐射剂量测试的实验结果 .结果表明电晕法制备的驻极体及其所建实验装置能够用于γ辐射剂量的测量 .In this paper, the application of the electret (made by corona charging) in γ radiation dose measurement is described. The description focuses on the setup for forming electret by corona charging and the designing and making of the electret dose measuring setup. Working principle of the dose measuring setup and its structure and special features are also described, with emphasis on the importance of these features to the accurate measurement of radiation dose. The experimental results of the electret charge stability and of the radiation dose measurement are given. These results indicate that both the electret and the setup are suitable for radiation dose measurement.
