摘要:
辐照后的玻璃可经电子自旋共振(ESR)波谱仪检测出ESR信号,包括本底信号、机械信号和辐射信号。ESR信号的大小与受照剂量基本成正比。当发生核事故或突发辐射意外时,可以通过对受照人员随身携带物品或事故区域内的玻璃进行ESR测量,快速估算事故剂量,评价事故的严重程度,并对受照人员进行及时的医学救治。玻璃具有廉价、化学惰性、刚度好、易于处理、普遍易得等特点,是一种很有前景的剂量估算物理剂量计。笔者主要对玻璃构成、剂量估算原理、ESR信号组成及其剂量学特性进行了探讨。
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.
