CORRELATION OF RADON CONCENTRATION LEVEL WITH MINING AND GEOLOGICAL CONDITIONS IN UPPER SILESIA REGION

摘要

It is established that radon concentration in dwellings is connected with the geological structure of the Upper Silesian Coal Basin, as well as the intensity and the depth of carrying out mining operations. The measurements revealed that radon level is higher in buildings located on outcropped Triassic layers than in those ones on Tertiary and Quaternary sediments. It is shown that the syncline regions are the zones of increased radiation hazard.
