It is shown that the relationship between mass attenuation coefficients and incoherent scattering radiation is not an inverse proportion but a power function over a wide range of atomic numbers (e.g. 5 B– 40 Zr and H 3 BO 3 –KBr). The experimental results are in good agreement with this theoretical prediction. A new method is recommended for matrix absorption correction in x‐ray fluorescence analysis using the power function of Rh Kα Compton peak intensity. The method has been experimentally proved to be correct and superior to the traditional scattering internal standard technique over a wide range of matrix compositions, partially in application to trace element determinations in heavy matrix absorption samples. © 1997 by John Wiley & Sons, Ltd.
