TRACKS DENSITY, radon concentration, radon exhalation rates and radium concentration were measured from ceramic tiles for both of glaze and clay by using the track technique, containing CR-39, to estimate the radiation exposure in the vicinity of ceramic tile. For ceramic tiles of wall, the average of tracks density, the radon concentration, radon exhalation rates and radium concentration were found in the range 230-356 tracks.cm-2, 389-600 Bq.m-3, 21-31 mBq.m-2.h-1, 16-25 Bq.kg-1, respectively. While for ceramic tiles of floor, the average of tracks density, the radon concentration, radon exhalation rates and radium concentration were found in the range 274-509 tracks.cm-2, 463-860 Bq.m-3, 25-46 mBq.m-2.h-1, 19-46 Bq.kg-1, respectively. The average level of radon concentrations caused by these ceramic tiles for Egyptian companies covering both of wall, floor, glaze and clay giving an annual exposure dose 22±2 mSv.y-1 which is higher than internationally recommended range.
