摘要

There has been great concern about the health risks associated with the exposure due to the natural radioactivity present in soil and building materials all over the world. In this context, soil and building material samples were collected from Gujranwala, Gujrat, Hafizabad, Sialkot, Mandibahauddin and Narowal districts of the Punjab province, Pakistan. Ra-226, Th-232 and K-40 concentrations were measured in these samples using the HPGe detector. From the measurements, mean radium equivalent activity, external and internal hazard indices as well as terrestrial absorbed dose rate were calculated. Average Ra-226, Th-232 and K-40 concentrations in soil and building material samples were found to range from 20 +/- 9 to 43 +/- 17 Bq kg(-1), 29 +/- 8 to 53 +/- 9 Bq kg(-1) and 98 +/- 38 to 621 +/- 189 Bq kg(-1), respectively. Average radium equivalent activity, external and internal hazard indices and annual effective dose equivalent were found to range from 69 +/- 25 to 165 +/- 32 Bq kg(-1), 0.18 +/- 0.09 to 0.45 +/- 0.09, 0.25 +/- 0.14 to 0.56 +/- 0.10 and 0.10 +/- 0.08 to 0.39 +/- 0.07 mSv, respectively. These values were compared with the published data and were found to be within acceptable limits. (C) 2008 Elsevier Ltd. All fights reserved.
