Abstract

Radical formation in 90Y-beta-irradiated D- and L-alanines was studied using ESR. It was observed that the relative radical concentration by beta-irradiation was distinguishably (13.9-21.5%) more in D-alanine than in L-alanine. Discussion was made on the possible mechanisms for the observed results.
