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.
摘要
利用电子自旋共振（ESR）研究了90Y-β辐照的D-丙氨酸和L-丙氨酸中的自由基形成。观察到，β辐照产生的相对自由基浓度在D-丙氨酸中比在L-丙氨酸中明显更高（高13.9 - 21.5%）。针对观察到的结果对可能的机制进行了讨论。
