This paper shows the influence of hardness on the beta backscattering coefficient from heat treated and plastic deformed carbon steel specimens. The observed effect cannot be explained as a change in the chemical composition of the sample (or effective atomic number). In order to explain the observed dependencies, it is necessary to take into account the structural defect and morphological changes of the different phases.
