title: Environmental radiation measurements using TLD-900 at the King Saud University Campus, Riyadh, Saudi Arabia.
abstract: To determine the baseline environmental radiation and resulting population exposure, natural background levels at the King Saud University campus were measured using CaSO4:Dy (TLD-900) discs. Measurements were made 1 m above ground level at 10 locations. Two different calculational methods were utilized to account for signal fading. In the first method, a fading correction factor was determined and used separately. In the second method, a separate correction factor for fading was not required because the determined calibration factor was carrying this correction. Results of the two methods were similar. Measurements were performed on a quarterly basis for a 2-y period (January 1988 to December 1989). The annual average dose rate was 565.4 +/- 27.1 mu Gy y-1 in air.
