Field radiation monitoring and radionuclide analysis of soils were performed at various geological areas in Taiwan. The field-observed dose rate was 0.031-0.107 μGy h. The dose rate ascribed to naturally occurring radionuclides in soils that were geologically characterized varied from 0.002 to 0.079 μGy h. A linear correlation was observed between the activity-derived and field-observed dose, which indicated that the absorbed dose rate from the cosmic rays is almost constant (0.030 μGy h) throughout the flat area on the island.
在台湾的不同地质区域进行了现场辐射监测和土壤放射性核素分析。现场观测到的剂量率为 0.031-0.107 μGy h。根据地质特征，土壤中天然放射性核素的剂量率从 0.002 到 0.079 μGy h 不等。活性衍生的剂量与现场观测到的剂量之间存在线性相关性，这表明来自宇宙射线的吸收剂量率在岛屿的平坦区域几乎是恒定的（0.030 μGy h）。
