AbstractThe K and L x‐ray emission intensities per 100 disintegrations have been calculated for some radionuclides using the latest adopted data for gamma‐ray intensities, electron capture and internal conversion coefficients for the parent nuclides, fluorescence yield values, Coster–Kronig transition probabilities, average total number of primary L shell vacancies produced in the decay of K shell vacancies and emission rates for various shells and subshells for the daughter nuclei. The results are in good agreement with theoretical and experimental values for the K x‐ray intensities. There are no experimental results available to compare with the present calculations for the L x‐ray intensities; however, there is a marked discrepancy in the Lα and Lβ intensities available on the basis of theoretica
