Dehydration of irradiated and non-irradiated asparagine monohydrate was investigated by means of a computer interfaced PerkinElmer
1B DSC in isothermal conditions and static atmosphere. Isothermal runs were performed at 358, 363, 368 and 373 K. Samples
were γ-irradiated at room temperature, using a 137Cs source with an activity of 3·1013 Bq and a dose rate of 4·102 Gy h−1, with irradiation times between 8–116 h. Isothermal kinetics were analyzed via the common factorized rate equation. Šesták-Berggren
conversion function was found to best fit the experimental data. Of the three fitting parameters, only the one associated
with the activation energy was found to follow a coherent variation with the exposure time. Even within this simple model,
that makes the activation energy a useful stability criterion within a set of similar samples.
