Abstract

Knowledge of accurate radio-isotopic signatures and chemical constituents is essential in assessing potential radiological hazards to the public and workers from exposure to NORM waste. For that reason, scale and sludge samples from Ghanaian oilfields were assessed using alpha spectrometry, gamma spectrometry, radon monitoring and scanning electron microscope techniques. Activity concentration of 238U, 232Th-series and 40K radionuclides for NORM residues have been evaluated. Fourteen trace elements were also identified and semi-qualitatively quantified. The obtained results clearly reflect that scale and sludge may present radiological risk for workers, public and environment.

加纳朱比利油田水垢和污泥天然放射性水平及相关放射性危害评估
了解准确的放射性同位素特征和化学成分对于评估公众和工作人员接触NORM废物的潜在放射性危害至关重要。因此,使用阿尔法光谱法、伽马光谱法、氡监测和扫描电子显微镜技术对加纳油田的水垢和污泥样本进行了评估。评价了238U、232Th系列和40K放射性核素对NORM残留物的活度浓度。还对14种微量元素进行了鉴定和半定性定量。所获得的结果清楚地反映了水垢和污泥可能对工人、公众和环境造成放射性风险。
