Abstract
The spectrum registration under rapid passage conditions (the second harmonic phase quadrature of the absorption signal) allows one to enhance substantially the sensitivity of tooth enamel and bone EPR dosimetry at a low accumulated dose. In the present work the dependencies of the radiation and background signals on EPR spectrometer parameters are described and the optimal conditions in RPM for EPR dosimetry are obtained.
摘要
在快速通过条件下的光谱记录（吸收信号的二次谐波相位正交）能够在低累积剂量时显著提高牙釉质和骨骼电子顺磁共振剂量测定的灵敏度。在本工作中，描述了辐射信号和背景信号对电子顺磁共振光谱仪参数的依赖性，并获得了电子顺磁共振剂量测定在快速通过模式下的最佳条件。
