摘要

福岛第一核电站事故发生后,一些空气辐射和地面辐射测量技术被应用于环境辐射测量。根据环境中空气剂量率的空间分布,这些方法已在不同情况下使用。在我们之前的研究中,针对目标环境的特点选择最有效的工具。然而,在同一环境下,机载和地面辐射测量结果尚未进行评估和比较。在本研究中,我们尝试用归一化均方误差参数对同一农场的机载和地面辐射测量结果进行定量评价。因此,对各种测量技术的可靠性进行了量化。利用该方法可以实现不同技术的比较,对有效监测环境中空气剂量率的空间分布具有重要意义。

Comparison of airborne and ground-based tools used for radiation measurement in the environment
After the Fukushima Daiichi nuclear power plant accident, some airborne and ground radiation measurement techniques have been applied to the environmental radiation measurements. These methods have been used in different situations depending on the spatial distribution of air dose rate in the environment. In our previous studies, the most effective tool was selected in response to the feature of targeted environment. However, airborne and ground radiation measurement results have not yet been evaluated and compared in the same environment. In this study, we attempted to quantitatively evaluate the results of airborne and ground radiation measurements with the parameter of normalized mean square error in the same farm. Consequently, the reliability of each measurement technique was quantified. The comparison of different techniques, which is important to effectively monitor the spatial distribution of air dose rate in the environment, could be achieved using this method.
