摘要

109

Cd X射线源是供油水分析仪测原油含水率用的。

109

Cd的半寿命为453天，它的衰变子体

109m

Ag发射22keV的X射线和88keV的γ射线，而能量为22keV的谱线的油水吸收系数相差较大，适用于油水分析仪测原油含水率。由于22keV的X谱线能量较低，为了尽量减少自吸收，要求源要薄而均匀，所以我们采用了电镀效率高、时间短，镀层薄而均匀、牢固的分子电镀法做源。测得源强为1×10

Cd is a radioisotope with a half-life of 453 days and its decay daughter

the

Cd is very suitable X ray source as oil-water analyser for the determination of fraction of water contained in oil(water/oil ratio). Considering the rather low energy of 22 keV X ray

we used the molecular plating method which has the advantages of high deposition efficiency

and short deposition time. The plating layer are thin

uniform

less self absorption and strongly adhesive to the base material. The intensity of
