本文研究了甘氨酸、丙氨酸及其碱金属盐在无水固态下的辐射化学。铯-137 γ辐照结果表明，样品溶解时主要释放出CO2和NH3。产率的相似性表明分解机理差异不大，与Tolbert假设的一般机理吻合良好。G（CO2）值为甘氨酸，1.02;丙氨酸，0.89;甘氨酸钠，0.43;甘氨酸钾，0.54;甘氨酸铷，0.91。其他产物及其G值对于甘氨酸为G（H2）= 0.1; G（NH3）= 4.3，G（CH 3 NH 2）= 1; G（-M）= 6，对于丙氨酸为G（H2）= 0.5; G（NH3）= 3.3; G（CH 3CH 2NH 2）= 2; G（-M）= 5。
The radiation chemistry of glycine and alanine as well as the alkali metal salts of glycine has been investigated in the anhydrous solid state. Results of cesium-137 gamma irradiation indicate CO2is the chief gaseous product with larger amounts of NH3being released upon dissolution of the samples. Similarity of yields indicates little difference in decomposition mechanism and good agreement with the general mechanism postulated by Tolbert. G(CO2) values were glycine, 1.02; alanine, 0.89; sodium glycinate, 0.43; potassium glycinate, 0.54; rubidium glycinate, 0.91. Other products and their G values were for glycine G(H2) = 0.1; G(NH3) = 4.3, G(CH3NH2) = 1; G(—M) = 6 and for alanine G(H2) = 0.5; G(NH3) = 3.3; G(CH3CH2NH2) = 2; G(—M) = 5.
