Effects of gamma radiation on solid sodium tartrate dihydrate (NaTA) were studied using electron spin resonance (ESR) spectroscopy. One main singlet located at g = 2.0034 and many weak lines located at low and high magnetic field sides were found in the irradiated samples. Dosimetric and kinetic features of the radical species responsible for the experimental ESR spectra were explored through the variations in the signal intensities with respect to applied microwave power, temperature and storage time. Activation energies of the involved radical species were also determined using data derived from annealing studies.
利用电子自旋共振（ESR）光谱研究了γ辐射对二水合酒石酸钠（NaTA）固体的影响。在辐照样品中发现了一个位于g = 2.0034的主要单重态以及位于低磁场和高磁场侧的许多弱线。通过信号强度随施加微波功率、温度和储存时间的变化，探索了产生实验ESR光谱的自由基物种的剂量学和动力学特征。还利用退火研究得出的数据确定了所涉及自由基物种的活化能。
