摘要：

Emanation thermal analysis, which measures the release rate of radon from a sample previously labelled with trace amounts of thorium-228 and radium-224 on its surface, makes it possible to reveal differences in the thermal behaviour of quartz sand before and after mechanical treatment by milling, and indicates the formation and thermal recrystallization of the highly disordered silica layer resulting from the mechanical activation of the sample.
