During years 2010-12 an automated, on-line and wireless outdoor measurement station of atmospheric radon, gamma dose rate and meteorological parameters was realised at the National Radiation Protection Institute (NRPI) in Prague. At the turn of the year 2013 an expansion of the existing station was completed. Under the project funded by the Czech Technological Agency a new updated station was established, additionally equipped with modules for measurement of atmospheric radon/thoron short-lived decay products, radon in water and soil and radon exhalation rate from soil. After the introduction of the station updated key detection parameters and benefits, its use for atmospheric modelling and monitoring is demonstrated. There are summarised results from the 3-year measurement period in the NRPI outdoor area in Prague and from simultaneous annual measurement performed by another similar station located near uranium mud fields in DIAMO, state enterprise, Stráž pod Ralskem. Observed seasonal and diurnal variations of atmospheric radon concentrations and variability of the equilibrium factor, F, are illustrated and compared.
2010年至2012年期间，在布拉格的国家辐射防护研究所（NRPI）建成了一个用于大气氡、伽马剂量率和气象参数测量的自动化、在线且无线的户外测量站。2013年初，对现有测量站进行了扩建。在捷克技术局资助的项目下，建立了一个新的升级测量站，该测量站额外配备了用于测量大气氡/钍短寿命衰变产物、水中和土壤中氡以及土壤氡析出率的模块。在介绍了该测量站的升级关键检测参数和优势后，展示了其在大气建模和监测中的应用。文中总结了在布拉格NRPI户外区域进行的为期3年的测量结果，以及由位于斯特拉日-波德-拉尔斯凯姆国营企业DIAMO的铀泥田附近的另一个类似测量站同步进行的年度测量结果。文中阐述并比较了观测到的大气氡浓度的季节性和日变化以及平衡因子F的变异性。
