Ground gamma-ray survey of the Solforata gas discharge area, Alban Hills-Italy: A comparison between field and laboratory measurements

► Comparison between two methodologies for gamma-ray spectrometry analysis of soil samples. ► Accuracy testing of a portable instrument for in situ measurements. ► High accuracy measurements in a very low background laboratory. ► Distribution of radionuclides in soils by both the techniques. ► Comparing field and laboratory surveys enabled the detection of radon degassing.
