Investigation upon Recycling of High Energy Electron Beam Irradiated Alanine Dosimeter

摘要

This paper presents the recycling possibility of irradiated alanine dosimeter via annealing methods. The alanine samples were irradiated under 10 MeV electron beam with the doses of 10, 30, and 60 kGy. The samples were stored in an oven with the different temperature and time. The fading effects of the EPR signal of the alanine samples were investigated, and the optimum time and temperature were found. Furthermore, the calibration curves have been drawn for the annealed samples. The stability of annealed alanine has also been examined. The results show that the optimum annealing time and temperature are 30 min and 200 °C, respectively. On the other hand, it was obvious that the obtained results were independent of the radiation dose.
