Granite paving is a hard wearing product, being ideal for use in driveways, patios, pathways‚ streetscapes and market places. Recently, several sidewalks were arranged in the Galati town, using as pavement materials granite slabs in various shapes and colors.
Because the levels of ambient radiation are not known, we measured the gamma radiation dose values with the aid of a DIGILERT portable radiometer1\0000+. Central areas of the municipality were chosen, where the granite slabs were mounted over long distances. Measurements results highlighted that in some areas granite sidewalk showed higher radioactivity level than in other locations and public parks of the town, the average dose rate ranging between 185 nSv/h and 234 nSv/h, with maximum values in the range 218-327 nSv/h.
