摘要：
Natural radioactivity has been measured from the soil samples collected from the Sind province of Pakistan. The measured activities of Ra-226, Th-232 and K-40 were found in the range of 18-47, 24-69 and 254-769 Bq kg(-1), respectively. The calculated values of the absorbed dose rate in air and the annual effective dose were in the range of 33-87 nGy h(-1) and 0.16-0.43 mSv, respectively. The measured results of activity were found compatible with the worldwide findings.
