摘要

为了提高低水平液体闪烁测量效果，改进计数瓶是提高液闪仪计数灵敏度的有效措施之一。周密的设计和精密的加工能使计数瓶中闪烁溶液的挥发量≤0.5mg/week。实验表明：计数瓶壁厚在1-1.5mm为最佳，对不同容积的金属盖金属托聚四氟乙烯计数瓶、金属罩计数瓶、金属表面发黑和抛光计数瓶及LKB公司计数瓶实测结果进行了比较。

Abstract

Improving the vial quality is one of the effective ways for increasing the sensibility of liquid scintillation counting. Based on careful design and precision processing

the amount of volatilized cocktail in a counting vial can be less than 0.5mg/week. The result indicates that the best thickness of vial-wall is about 1—1.5mm. Measurements of characteristics are made for teflon counting vials with metal shield and different volumes

vials with metal surface blacked or polished

and vials from LKB Company. The results are compared and discussed.
