A Monte Carlo model is derived for the simulation X‐ray fluorescence from homogeneous samples including primary, secondary and tertiary fluorescence events. The model is designed specifically for an annular radioisotope source mounted coaxially with a circular detector. It is verified with analytical relationships for the limited case of fixed sample entrance and exit angles. The results indicate accuracies (2% or better) that are well within our knowledge of X‐ray fluorescence parameters (such as fluorescence yields), yet can be calculated with very modest (15 seconds) digital computer calculation time.
