摘要

我们报告了在暴露于铯-173伽马辐射时对光学闪烁光纤的原位监测的初步结果。我们测量了可见光光谱中光纤透光率随时间的变化。我们观察到500 nm以下的区域降解迅速而彻底，而500 nm以上的区域失去清晰度的速度较慢。

Results from In Situ Monitoring of Radiation Damage of Scintillation Fibers

We report preliminary results from in situ monitoring of an optical scintillating fiber while being exposed to a cesium-173 gamma radiatior. We measured the degradation of fiber transmittance across the visible spectrum as a function of time. We observed that the region below 500 nm was degraded quickly and thoroughly while wavelengths above 500 nm lost clarity more slowly.
