手表玻璃作为核事故剂量的ESR检测材料

THE WATCH GLASS USE FOR ESR DOSIMETRIC MATERIAL IN NUCLEAR ACCIDENT

用电子自旋共振方法研究了^(60)Coγ射线照射石英手表玻璃的基本剂量学特性。实验结果表明,在0—50 Gy范围内,手表玻璃的ESR信号强度与辐射剂量呈线性关系(r=0.9993),可测剂量下限低于2 Gy。提示手表玻璃可以做为一种有效的核事故剂量ESR检测材料。

Electron spin resonance technique was used to investigate the ESRcharacteristic of watch glass irradiated with γ-ray. The result showed that signalintensity has a linear relation with irradiation dose in range of 0--50 Gy, the lowerlimit of detectable dose is below 2 Gy. It suggests that watch glass can be a kind ofapplicative material for nuclear accident dose evaluation.
