摘要

The preliminary results of soil gas radon concentrations and permeability inudsitu measurements carried out in 39 primary schoolyards infour neighbouring municipalitiesudof Eastern Macedonia are presented in this paper. At each location,udthe radon was sampled at 80 cm depth and measured by ionization chamber. Usingudthe RADON-JOK equipment the measurement of permeability was performedudin the same point. The infield campaigns were conducted in January and Juneud2016. Radon concentrations and permeability ranged: from 7 to 84 kBq/mudandudfrom 1:7 � 10ud13udto 7:8 � 10ud12udmud2udin January; and from 8 to 60 kBq/mudand fromud2:5 � 10ud14udto 1:9 � 10ud11udmud2udin June. Spatial variations within investigated areaudexpressed by the coefficient of variation were lower for radon concentrations thanudfor permeability in both sets of measurements. The variations of radon were: 61%udin January and 56% in June whereas 102% in January and 149% for permeabilityudwere obtained. The resulting radon potential of the measuring sites varied fromud3 to 49 in January and from 2 to 38 in June. The correlation between observedudvalues and its relation with lithostratigraphy was confirmed.ud3ud3
