An x‐ray fluorescence technique involving a 30 mCi 238 Pu as a source of primary radiation and a two‐channel thin NaI(Tl) crystal spectrometer was developed for the analysis of coal ash samples. The geometry of the source–target–detector assembly is described. The ash content is estimated using an x‐ray backscattering method which includes compensation for iron x‐ray fluorescence. About 120 Indian coal samples were analysed and the results show that the ash content varies from 10 to 40%.
