Abstract: This study evaluates radon exhalation rate from 10 different granite stones, used for building construction in Iran.Radon exhalation rate ranged from non-detectable to 0.6 Bq m-2 h-1. Six samples had exhalation rate above detectable level. Asignificant statistical relationship between radon exhalation rate with 226Ra and 232Th indicated that 226Ra and 232Th wereresponsible for radon exhalation from granite stones.
