本工作使用~(136)Ba(n,2n)~(137m)Ba反应,对十种地质样品中的钡进行了测定,还对部分样品中的硅(利用~(28)Si(n,p)~(26)Al反应)和钡进行了同时测定。所得结果同化学分析方法的结果相一致,能满足地质规范对准确度和精密度要求。
In this work, barium in ten geological samples was measured using ~ (136) Ba (n, 2n) ~ (137m) Ba reaction. ) ~ (26) Al reaction) and barium simultaneously. The results are consistent with the results of chemical analysis methods to meet the geological specifications of the accuracy and precision requirements.
