|
|
| Abundance of resinized biotite results in the activities of mining and exploration in the Jos since 1904. The mining has been operating for the past 50 years, and radioactive nature of the minerals was realized not before 1974. This work intends to unveil the extent to which K40, Ra226, and Th232 transfers from soil to water and various species of food crops in Bassa. The results revealed that, the TF for different trace elements in soil-edible plants for all points decreased in the order P12 (0.716) > P04 (0.660) > P07 (0.581) > P02 (0.579) > P06 (0.574) > P10 (0.568) > P05 (0.542) > P08 (0.540) > P01 (0.534) > P09 (0.532) > P03 (0.520) > P11 (0.517). Considering the individual radioactive traces, the TF decreased in the following order: 232Th (0.666) > 226Ra (0.557) > 40K (0.473). The total TF for different trace elements in soil-water for all points decreased in the order P04 (0.930) > P06 (0.787) > P07 (9.786) > P10 (0.780) > P08 (0.765) > P03 (0.759) > P11 (0.755) > P02 (0.720) > P01 (0.665) > P05 (0.600) > P12 (0.576) > P09 (0.398). Also considering the individual radioactive traces, the TF decreased in the order 232Th (0.828) > 40K (0.715) > 226Ra (0.587). It can be concluded that the water and edible plants in the study area are good for public consumption, though, regular checking of radioactive traces in the study areas are recommended.
