Radical formation in D- and L-alanines was studied using ESR after internal3H-β-irradiation under the situation in which the contribution of Bremsstrahlung to form the radicals is assumed to be considerably less than the case of9 0Y-β-irradiation. It was demonstrated that the relative radical concentration by the β-rays was distinguishably higher in D-alanine than in L-alanine. Thus the asymmetry found in these experiments in the radical formation of the alanines may be attributed to the different interaction between the polarized electrons and the two enantiomers.
