| Abstract | ||||
| The activity concentrations of natural radionuclides 226Ra, 232Th and 40K and radiological hazards for soil samples from New Assiut City have been measured by using gamma spectrometry (HPGe) detector. The measured average activity concentrations of 226Ra, 232Th and 40K were 20.50±1.28 Bq.kg-1, 16.37±2.077 Bq.kg-1 and 189.51±0.34 Bq.kg-1 respectively. The activity concentrations from this study were compared with the reported data from other countries. The Raeq values of all samples were lower than the limit of 113 Bq.kg-1, equivalent to a gamma dose of 1.5 mSv.a-1 recommended by OECD. With average annual dose 0.07 mSv.y-1, this value is about 7 % of the 1.0 mSv.y-1 which is recommended as the maximum annual dose per person by the International Commission on Radiological Protection. | ||||
