Abstract

The preliminary results of soil gas radon concentrations and permeability in situ measurements carried out in 39 primary schoolyards infour neighbouring municipalities of Eastern Macedonia are presented in this paper. At each location, the radon was sampled at 80 cm depth and measured by ionization chamber. Using the RADON-JOK equipment the measurement of permeability was performed in the same point. The infield campaigns were conducted in January and June 2016. Radon concentrations and permeability ranged: from 7 to 84 kBq/m and from 1:7 � 10 13 to 7:8 � 10 12 m 2 in January; and from 8 to 60 kBq/m and from 2:5 � 10 14 to 1:9 � 10 11 m 2 in June. Spatial variations within investigated area expressed by the coefficient of variation were lower for radon concentrations than for permeability in both sets of measurements. The variations of radon were: 61% in January and 56% in June whereas 102% in January and 149% for permeability were obtained. The resulting radon potential of the measuring sites varied from 3 to 49 in January and from 2 to 38 in June. The correlation between observed values and its relation with lithostratigraphy was confirmed. 3 3
