将~(241)Am长入NaI(Tl)晶格中组成恒定幅度脉冲光源,广泛地应用于光电倍增管增益监测。现在国外已有商品出售,表1列出荷兰Harshaw公司生产的NaI(Tl+~(241)Am)产品性能,反映了脉冲光源的当前水平。
The formation of constant amplitude pulsed light source with ~ (241) Am into NaI (Tl) crystal lattice is widely used in photomultiplier tube gain monitoring. Now that foreign products are sold, Table 1 shows the performance of NaI (Tl + ~ (241) Am) produced by Harshaw in the Netherlands, which reflects the current level of pulsed light sources.
