EPR investigation of the gamma radiation response of different types of glasses
چکیده انگلیسی

Several types of laboratory glasses such as: “Jena”, “Rasotherm”, “Thüring” as well as window and windscreen glasses were studied by the method of EPR spectroscopy as possible emergency radiation dosimeters for γ-ray irradiation. The most appropriate values of modulation amplitude and microwave power were found to obtain best sensitivity for the measured signals. Dose measurements have shown a linear dependence between the EPR signal intensity of radiation created defects in glasses and applied dose in the dose range 50–500 Gy. “Thüring” glass was found to be the most sensitive sample to radiation. The magnitude of window glass absorbed dose was evaluated as the difference between the intensity of its EPR signal recorded after irradiation and the background signal, obtained after thermal relaxation of the former.
