Abstract |
|
|
| Plants received these radioactive trace elements from soils through ionic exchange, redox reactions, precipitation-dissolution. The same trace elements can contaminate water through erosion, where radioactive trace elements are flushed to our rivers and streams and we consume them. Contamination factor of soil, water and edible plants is studied using an index called Contamination Factor (CF). The result revealed that, the total CF for different trace elements in soil based on sample points decreased in the order P06 (1.66)>P09 (1.65)>P11 (1.61)>P10 (1.55)>P08 (1.46)>P01 (1.43)>P03 (1.42)>P02 (1.34)>P07 (1.21)>P12 (1.20)>P05 (0.86)>P04 (0.75), considering the individual trace elements, the total CF decreased in the 232Th (1.90) > 40K (1.21) > 226Ra (0.92). The total CF for different trace elements in water based on sample points decreased in the order P06 (1.33)>P11 (1.29)>P10 (1.23)>P08 (1.14)>P01 and P03 (1.09)>P02 (1.02)>P07 (0.97)>P12 (0.87)>P04 (0.65)>P09 (0.58)>P05 (0.54), considering the individual trace elements, the total CF decreased in the order: 232Th (1.59) > 40K (0.79) > 226Ra (0.58). The total CF for different trace elements in edible plant based on sample points decreased in the order of Shuwaka (1.01)>Water Leaf (0.98)>Rogo (0.92)>Zogale (0.89)>Karkashi (0.83)>Kuka (0.81)>Kabeji (0.79)>Rama (0.77)>Yakuwa (0.75)>Ugu (0.58)>Alayyahu (0.47)>Yateya (0.46), considering the individual trace elements, the total CF decreased in the order 232Th (1.28) > 40K (0.55) > 226Ra (0.48).
