A radioisotope excited XRF method based on the use of five 10-mCi 125I point sources arranged in a newly designed configuration is applied to the bromine determination in very small blood serum samples (less than or equal to 50 microL). The possibility of determination of 0.05 micrograms Br in blood serum during 100 s counting time with a standard deviation of +/- 10% is described. The simplicity and low cost of the present method are major advantages over the other nondestructive methods and render it suitable for medical laboratories.
一种基于使用五个10毫居里的¹²⁵I点源以新设计的配置排列的放射性同位素激发X射线荧光法，被应用于测定非常少量的血清样本（小于或等于50微升）中的溴。描述了在100秒计数时间内测定血清中0.05微克溴的可能性，标准偏差为±10%。与其他无损方法相比，本方法的简单性和低成本是主要优点，使其适用于医学实验室。
