| Abstract | ||
| In this study the activity concentrations of natural radioactive elements 226Ra، 40K، 232Th and their transfer factor for 36 samples of soil and vegetables in four agriculture locations (Rabea، Al-Rashedia، Hamam Al-Aleel and Al-Salamia) were calculated. The average activity concentrations of 40K، 226Ra، 232Th in soil were found to be 624.66±75.4، 20.64±3.63 and 6.73±1.84 Bq/kg respectively in the four locations. Their values in dry vegetables were found to be 314.07±36.3، 7.9±1.63 and 1.68±0.92 Bq/kg and in fresh vegetables were found to be 31.2±7.9، 0.74±0.23 and 0.175±0.07 Bq/kg respectively. The average transfer factors of 40K، 226Ra، 232Th from soil to dry vegetables were found to be 0.507±0.04، 0.386±0.06 and 0.216±0.03 while their values to fresh vegetables were found to be 0.05±0.014، 0.037±0.013 and 0.022±0.007 respectively in the four locations also. The average values of absorbed dose and the total annual dose were found to be 0.04±0.0037 μGy/h، 70.93 μSv/y respectively | ||
