提示. .γ. .热中子诱导核反应产生的射线已被用来测量工业和标准材料中痕量的B和Cd。该技术可快速无损分析> 0.05 ..重复分析表明该方法的精密度为5%。大量Na的存在降低了B分析的准确性和精密度。该技术还提供了一种测定Cd的方法，尽管它不够灵敏，不能作为常规方法的实用替代方案。
Prompt ..gamma.. rays from thermal neutron induced nuclear reactions have been used to measure trace quantities of B and Cd in industrial and standard materials. The technique provides a rapid nondestructive analysis for > 0.05 ..mu..g of B. Repetitive analyses show the method to have a precision of 5%. The presence of large quantities of Na degrades the accuracy and precision of the B analysis. The technique also provides a method for the determination of Cd although it is not sufficiently sensitive to provide a practical alternative to more conventional methods.
