| Abstract: | Photonuclear activation and high resolution gamma spectrometry have been used to determine nondestructively 28 trace elements
in coal. The samples and synthetic multielement standards were simultaneously irradiated in the bremsstrahlung beam at 18
and 30 MeV maximum energies. Taking into account the contribution of the main possible interferences, limits of detection
between 0.2 and 125 μg·g−1 were obtained.
