This paper describes two methods for the scattering and absorbed correction in a radioisotope source excited X-ray fluorescence analysis technique
that is two channel counting method and slope correction method. In the two channel counting method
the matrix effect can be controlled to about ±1% by using a two channel pulse height analyzer. The slope correction method has been applied to the thickness gauge for on line measurement of the thickness of a magnetic layer deposited on the tape. The accuracy of the measurement of the thickness is about ±5% (95% confidence level) .
