Dose-rate monitoring instruments measure the ambient dose equivalent and hence are crucial for protecting workers from radiation exposure. Although plastic scintillation detectors (PSDs) are ideal equipment for dosimetry, they are rarely used owing to the lower detection efficiency than other scintillation detectors. In this study, we acquired ten types of G(E) functions to utilize a PSD in spectroscopic dosimetry using the least-square and first-order methods. The energy response of PSD was much improved in terms of dose evaluation.
剂量率监测仪器测量环境剂量当量，因此对于保护工人免受辐射照射至关重要。尽管塑料闪烁探测器 (PSD) 是用于剂量测量的理想设备，但由于其探测效率低于其他闪烁探测器，因此很少使用。在这项研究中，我们使用最小二乘法和一阶方法获取了十种 G(E) 函数，以在光谱剂量测量中使用 PSD。在剂量评估方面，PSD 的能量响应得到了很大改善。
