摘要
本文研究了YS-1玻璃在γ射线辐照下的剂量学特性。结果表明,YS-1玻璃具有量程范围宽(5×10~2～10~5Gy)、衰退小(一口内光密度变化△A【6％,一星期内△A【14％;γ线辐照后用沸水煮20分钟,24小时内光密度基本不变)、不怕光照和耐潮湿等特点,可作为一种较好的用于辐照加工的常规玻璃剂量计。
The dosimetry characteristics of the YS-1 glass irradiated by γ-ray were studied. The results show that the YS-1 glass is characterized by wide dosage (measuring range 5×10~2～10~5Gy) and slow decay (the change of light-density △A<6% in one day, △4<14% in one week, and without any change of light-density in 24 hrs when it has been boiled for 20 minutes in 100℃ water after γ-ray irradiation), and is light-moisture resistant and so on. It is a fit routine glass dosimeter for the radiation processing.
