Abstract: Electron spin resonance(ESR) signals, such as background, mechanically-induced, radiation-induced signals, can be detected in irradiated glass by ESR spectroscopy. ESR signals are set proportional to the dose. When a nuclear accident or sudden radiation accident occurs, the ESR measurement of the glass can quickly estimate the dose. Then the severity of the accident can be evaluated, and the medical treatment of the injured can be effectively performed. The use of glass samples as radiation detectors has several advantages, such as chemical inertness, rigidity, insolubility, small size, low cost, and rifeness, that make them especially attractive. In this paper, the composition of glass, the principle of dose estimation, and the composition of the ESR signal and its dosimetry characteristics are discussed.
