A new paper from A. Grygier and colleagues at the Central Mining Institute (GIG) in Poland has been published with results from WP2 (Exposure) of RadoNorm. The paper titled Two-year assessment of radon exposure in the underground tourist route in the Historic Silver Mine in Tarnowskie Góry (Poland) was published in Scientific Reports and presents the results of a two-year radon risk study conducted at the Historic Silver Mine in Tarnowskie Góry. Continuous measurements of radon activity concentration were carried out in three-month cycles at 30 points distributed along the tourist route. Based on the collected data, seasonal correction factors considering seasonal variations in radon activity concentration (SCF) were determined. In addition, the spatial variation of radon activity concentration was studied at selected locations of the mine at different heights of the location of the detectors and their distribution on opposite sides of the excavation. Based on the collected data, effective doses were calculated.
