  • Abstract:
    It was prepared a reference material from a soil with high thorium concentration from a region with high natural radioactivity. Performed tests using gamma spectrometry and statistical programs showed that the prepared material was homogeneous and enough stable to be used as an in-house reference material in intercomparison exercises.
