摘要

利用伽马射线能谱法测量了尼日利亚西南部某些屠宰场周围的屠宰场废物和溪流及河流沉积物中天然放射性核素的浓度。在屠宰场废物中，牛粪样品中获得的活性浓度高于血液和骨灰样品中获得的活性浓度。沉积物40K、238U和232Th的平均活度浓度分别为290.04±156.84、22.02±4.14和50.42±18.90 Bq kg−1。计算了吸收的γ -室内剂量率和其他辐射健康指数，以便评估与在住宅建设中使用沉积物有关的辐射危害。所获得的数值低于科委会建议的安全和标准限值。因此，可以说，屠宰场周围各河流和溪流的沉积物是安全的，可以用于建造建筑物，而不会引起不必要的辐射健康问题。

Determination of natural radionuclides in abattoir wastes and sediments from rivers and streams around selected abattoirs in Southwest Nigeria

The concentrations of natural radionuclides in abattoir wastes and sediments of streams and rivers around selected abattoirs in Southwestern Nigeria have been measured using gamma-ray spectrometry. In abattoir wastes, the activity concentrations obtained in cow-dung samples are higher than those obtained in blood and bone ash samples. For sediment, the mean activity concentration of 40K, 238U and 232Th obtained is 290.04 ± 156.84, 22.02 ± 4.14 and 50.42 ± 18.90 Bq kg−1, respectively. The absorbed gamma-indoor dose rates and other radiological health indices were calculated in order to assess the radiological hazards associated with the use of the sediments in construction of dwellings. The values obtained were less than the recommended safe and criterion limits by UNSCEAR. It is sufficient to say therefore that sediments from the respective rivers and streams around the abattoir sites are safe and can be used for construction of buildings without undue radiological health concerns.
