Natural radioactivity in soil in the Baluchistan province of Pakistan.
The measurements of natural radioactivity and the assessment of radiological hazards in the soil samples of Baluchistan province of Pakistan have been carried out using HPGe detector. The soil gas radon activities in these areas have also been measured using lucas cell technique. The measured activities of (226)Ra, (232)Th and (40)K were found in the range of 15-27, 20-37 and 328-648 Bq kg(-1), respectively. The calculated absorbed dose rate in air and the annual effective dose were in the range of 35-59 nGy h(-1) and 0.17-0.29 mSv, respectively. Radon activity in the soil gas was found in the range of 357-2476 Bq m(-3).
