Ambient dose rate surveying has the objective, in most cases, to quantify terrestrial radiation levels. This is true in particular for Citizen Monitoring projects. Readings of detectors, which do not provide spectrally resolved information, such as G-M counters, are the sum of contributions from different sources, including cosmic radiation. To estimate the terrestrial component, one has to subtract the remaining ones. In this paper, we investigate the cosmic response of two particular monitors, the bGeigie Nano, which has been used extensively in the Safecast Citizen Monitoring project, and its upgraded version, the new CzechRad, which uses the same G-M detector, and show how the local contribution of cosmic radiation can be estimated.
在大多数情况下，环境剂量率测量的目的是量化陆地辐射水平。这在公民监测项目中尤为如此。探测器的读数，如盖革-弥勒计数器，不提供光谱分辨信息，是包括宇宙辐射在内的不同来源贡献的总和。为了估计陆地成分，必须减去其他成分。在本文中，我们研究了两种特定监测仪的宇宙响应，一种是在Safecast公民监测项目中广泛使用的bGeigie Nano，另一种是使用相同盖革-弥勒探测器的升级版新捷克辐射仪，并展示了如何估计宇宙辐射的本地贡献。
