Abstract AR
لقد تم إجراء قياسات مطيافية أشعة جاما لمحتوى النويدات المشعة و المعادن الثقيلة في عينات تربة من مواقع تفريغ النفايات في مدن مختارة في جنوب غرب نيجيريا، حيث تم تحديد مستويات التراكيز الفعالة الناتجة من 214Bi, 210Pb, 109Cd, 137Cs, 228Th, 226Ra, 40K و 208Ti في العينات باستخدام مكشاف Ge متحد المحور.
إن أعلى تراكيز للنويدات المشعة 228Th, 226Ra, 40Kو 137Cs هي 132 ± 10, 68 ± 7, 357 ± 12 و 0.96 BqKg-1 في مناطق أدو، و أبيكوتا، و لاجوس و إبادان بالتتابع، في حين كانت أقل تراكيز هي 22 ± 2, 40 ± 5, 180 ± 6 و 0.19 Bqkg-1 في مناطق أكورا، و أدو، و أوسوجبو و ابيكوتا بالتتابع.
إن أعلى تراكيز للمعادن الثقيلة 214Bi, 210Pb, 208Ti و 109Cd هي 104 ± 7, 46 ± 5, 35 ± 1 و 49 ± 1 Bqkg-1 في مناطق لاجوس.
و إبادان و أدو، في حين كانت أقل تراكيز هي 17 ± 2, 20 ± 3, 5 ± 0.24 و 40 ± 1 Bqkg-1 في أدو و إبادان بالتتابع.
و قد تم تسجيل أعلى و أقل معدل قيم جرعة الهواء الطلق الفعالة في لاجوس و إبادان.
Abstract EN
Gamma spectroscopic assays of radionuclide contents and heavy metal in soil samples from waste dump sites in selected cities in southwestern Nigeria were carried out.
The activity concentration level due to 40K, 226Ra, 228Th, Cs, 109Cd, 210Pb, 214Bi, and 208Tl in the samples were determined using coaxial-type Ge detector.
The maximum concentrations of 40K, 226Ra, 228Th, and 137Cs are 357 ± 12, 68 ± 7, 132و ± 10, and 0.96 Bqkg-1 at Ado, Abeokuta, Lagos and Ibadan; while the minimum concentrations are 180 ± 6, 40 ± 5, 22 ± 2, and 0.19 Bqkg-1 at Akure, Ado, Osogbo, and Abeokuta, respectively.
The maximum concentrations of heavy metals 208Ti, 210Pb, 214Bi, and 109Cd are 35 ± 1, 46 ± 5, 401 ± 7, and 49 ± 1 Bqkg-1 at Lagos, Ibadan, and Ado, while the minimum concentrations are 5 ± 0.24, 20 ± 3, 17 ± 2 and 1 ± 40 Bqkg-1 at Ado and Ibadan, respectively.
The highest and the lowest average outdoor effective dose rates were recorded at Lagos and Ibadan.
