Naturally occurring radioactive materials (NORM) have been determined in fly and bottom ash collected from four major Syrian power plants fired by heavy oil and natural gas. (210)Pb and (210)Po were the main NORM radionuclides detected in the fly and bottom ash. (210)Pb activity concentrations have reached 3393±10 Bq kg(-1) and 4023±7 Bq kg(-1) in fly ash and bottom ash, respectively; lower values of (210)Po were observed due to its high volatility. In addition, (210)Po and (210)Pb annual emissions in bottom ash from mixed (heavy oil and natural gas) fired power plants varied between 2.7×10(9)-7.95×10(9) Bq and 3.5×10(9)-10(10) Bq, respectively; higher emissions of (210)Po and (210)Pb from gas power plants being observed. However, the present study showed that (210)Po and (210)Pb emissions from thermal power plants fired by natural gas are much higher than the coal power plants operated in the World.
已在四家主要的叙利亚重油和天然气火力发电厂的飞灰和底灰中确定了天然放射性物质（NORM）。（210）Pb 和（210）Po 是在飞灰和底灰中检测到的主要 NORM 放射性核素。飞灰和底灰中的（210）Pb 活度浓度分别达到 3393±10 Bq kg(-1) 和 4023±7 Bq kg(-1)；由于（210）Po 挥发性高，观察到较低的（210）Po 值。此外，混合（重油和天然气）燃烧的发电厂底灰中的（210）Po 和（210）Pb 年排放量分别在 2.7×10(9)-7.95×10(9) Bq 和 3.5×10(9)-10(10) Bq 之间变化；从燃气发电厂观察到（210）Po 和（210）Pb 的排放量较高。然而，本研究表明，天然气热电厂的（210）Po 和（210）Pb 排放量远高于世界上运行的燃煤电厂。
