Abstract

: This residential site consisting of three buildings was chosen because it is highly populated and in the center of the city of Riyadh. The dosimeters were kept in the buildings for a period of nine months from January to October, 2001. The radon average concentration found as (32 +-2) Bqm-3, (40 +- 3) Bqm-3 and (59+-6) Bqm-3 Foom in buildings one, two and three are respectively. In this study a consistent trend of high radon concentration in small rooms than large ones may indicate poor ventilation in small rooms. The statistical analysis shows that 75% of the values are equal or less than 50 Bqm-3. It is also seen that 98% of the measured values are less than the safe limit of 148 Bqm-3 set by the Environmental Protection Agency of the U.S.A. It can therefore be concluded that these buildings may have no potential health hazard of Radon.
