Abstract The reaction rate is sometimes thoroughly described by several kinetic models simultaneously. In this case, the discrimination of the particular model may be challenging. Herein, we demonstrate that a change in the rate-limiting step of a re

IntroductionRadiobiological studies at low dose rates allow us to improve our knowledge of the mechanisms by which radiation exerts its effects on biological systems following chronic exposures. Moreover, these studies can complement available epidem
