| Background: Results are presented on some dosimetric characteristics of Sife – Eldeen dosimeter based on the radiation induced conductivity (RIC) of 3.5 M aqueous urea solutions. The studied characteristics were the response (RIC) of Sife – Eldeen dosimeter in broad ranges of absorbed dose, dose rates and at different irradiation temperature. Materials and Methods: Kent EIL5007 conductivity meter (Kent industrial measurements–Brown Boveri) was used for the measurement of samples RIC. Results: RIC of 3.5M urea aqueous was studied at low (0 – 462 Gy), as well as, at high (0 - 2592 kGy) absorbed radiation dose ranges. The coefficient of variation CV%, associated with RIC measurement of 3.5 M urea solution as a function of absorbed radiation dose, was found to be not more than 3.5% for both high and low absorbed radiation dose ranges. The effect of dose rate on RIC was studied in the range 0.035 - 5.969 kGy/h. The temperature effect on this system, at different doses, was also studied. Conclusion: The obtained results show the importance of using this dosimeter for dose evaluation in industrial gamma radiation processes , as well as in medical fields. Iran. J. Radiat.
