Abstract: 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.

Key words: electret, corona charging, electret dosimeter, ionising radiation
