γ射线辐照和阳光照射对ZF6铅玻璃透光率的影响
|
摘要
通过实验研究ZF6铅玻璃在~(60)Co放射源相同剂量率不同累积剂量照射下透光率的变化规律。将辐照后的铅玻璃在室外阳光下、室内自然光下和不透光的抽屉中放置观察,发现阳光照射对铅玻璃辐照着色的恢复起着重要作用,在建立铅玻璃透光率随辐照时间变化的数学模型时,室内自然光对铅玻璃透光率的影响可忽略。实验数据验证了受辐照时铅玻璃透光率的变化与辐照时间符合指数函数关系。根据文献资料推导出铅玻璃透光率变化与光照时间为线性函数关系,但发现其与实验数据的符合程度较差,本文根据样条曲线插值法推导出铅玻璃透光率与光照时间为二次函数关系,与实验数据的符合效果较好。
The transmittance variation of ZF6 lead glass which was irradiated by ~(60)Co under the same dose rate but different cumulative doses was researched through experiment.By putting the irradiated lead glass exposed on the radiation of sunshine outdoors,indoors nature light and dark drawer separately,the effect of sunlight exposure on the recovery of glass coloring was studied.The results show that the sunlight plays a significant role in the recovery of radiation coloring of lead glass,and the effect of indoors nature light to lead glass transmittance can be neglected when building the mathematical model of the relationship between the lead glass transmittance and the radiation time.The experimental results are verified that the lead glass transmittancepresents exponential relevant to irradiation time.According to the literature data,the relationship between the lead glass transmittance and its illumination time is linear,but the results by the relationship and the actual values are in poor agreement.Through the spline curve interpolation method,the relationship of the lead glass transmittance and its illumination time is a quadratic function,which gets a good agreement.
