Visited South Terras Mine today, but only stayed in the vicinity and didn't enter the private property. Still very high readings and the alarm went off already in the car 300m away. The dip in the measurement results from a detour to a neighboring field to get a different view. Was really surprised about the radiation levels - over 500 mySv/h without even being close to the mine! The spectrum indicates Bi 214 as part of the Radium chain
