Abstract
With the aid of a NaI (Tl) scintillation spectrometer the internal Bremsstrahlung and the atomic ionisation for the forbidden transitions 90Y and RaE have been studied. The results on the Bremsstrahlung are in accord with the simplified theory of Knipp and Uhlenbeck; those on the K ionisation with the formula of Levinger 0.92/Z2 while that of Migdal 0.64/Z2 gives a value too small.
